Sounds like a memory issue.

• What are the image sizes?
• How many in the set?
• What have you selected the output size to be?
• Are you using a panohead?
• Have you found the "correct" NPP No Parallax Point?

You need to provide more information so we can take a stab and finding your problem and thus, a possible solution.

I suggest first of all that you attempt to stitch a limited amount of images. Say 6 in total and see if you get a result.

Really if you are serious about panorama making you most definitely require a panohead so that you can rotate around the NPP. Of course the position of the NPP must first be set to match your camera/lens combination. Without a panohead set up correctly your success will be limited at best. You would most likely have success with stitching images that are landscapes where things are far off in the distance, but the closer the objects become the more the parallax will come into effect.

Let us know how you get on stitching a smaller amount of images (partial panorama).

I am not using a panohead but the tripod I am using rotates and has degree measurements on it so I feel like it's essentially the same thing.

I can assure you it is not. The NPP is a set point of a lens known as the Entrance Pupil and this is the point you must rotate around to avoid parallax. (for a long time mistakenly called the Nodal Point)

OK, so it appears you are hitting your memory limits. What is your computer specs? Amount of RAM etc?

Panoheads are available with and without the ability to tilt. You need to use the correct version. The NPP will be worked out using known methods.

Useful starting points can be offered once we know what camera body and lens you are using.

Look to these links for more on setting/finding the No Parallax Point

• The Grid
• Finding the NPP
• Zoning in on the NPP via nadir view

These three tutorials should see you sort the NPP out if you follow them correctly.

Once I know your equipment I can advise better on what panohead is best suited for your requirements. 71 shots is a lot of images. You might be better off with a wider lens like a Wide Angle or Fisheye depending on what you plan to use the final stitched image.

I.E: A fisheye can cover a full 360x180 with as little as 3 to 8 shots on a DSLR.

I have been moving the camera in very small increments but I am still getting a choppy distorted image in places were there is a seam between two pictures.

Any help or advice would be greatly appreciated.

You also need to be careful of too much overlap 20 to 30% is recommended, more than this will confuse the stitcher. So you must rotate around the NPP and shoot so that you have optimal overlap between images.

OK, so you got a panohead - great!

• What did you buy?
• What camera and what lens are you using?
• What lens are you using for the 45 images?
• What Fisheye lens did you buy?
• Have you found the NPP? Really?

You still haven't told us what computer equipment you are running

• What is your CPU?
• How much RAM do you have?

Sometimes you cannot get matching control points between images because

• The images lack information (lack of definable objects or repetitive objects that confuse)
• Poorly exposed images (too bright or too dark)
• Or not enough overlap

The no show in Tourweaver preview window could be

• Under powered computer CPU and/or RAM
• Graphics card under powered and not up to the job or incompatible
• Too many programs running at the one time (programs running in the background)
• The latest version of Flash browser plug-in is not installed correctly
• Program install is corrupted 

Unfortunately you will have to work through these things to find the answer. Some things you mention will be easier to answer once you have supplied more information. As it stands, all I can offer is an educated guess.
