After a LOT of experimenting and having thisprogram switch between working wonderfully and force closing upon launch, I have come to the conclusion that it is the pictures themselves!
So, the first thing you need to do is to check that none of your pictures (and/or movies) are not corrupted. I found that the best way to do this is to open the Gallery app and browse through all your files. Youcan use the view in which multiple files are displayed as thumbnails (as opposed to a single full sized picture view). If a file is corrupted, then it will not generate a thumbnail for it. Instead, the thumbnail will remain black and when you tap on it, a full size image will not appear. Instead, a message about the image not being able to be shown will be there.
If you find something corrupted, then delete it via the Gallery and try the 3d Browser again.
The second thing I noticed as of 5 minutes ago:
After a long time of no problems, the 3d Browser decided to stop working today, so I did what I just explained about searching for corrupted images... to my surprise, all of myimages were fine.
I once again opened the Gallery app and noticed something odd, but the only way I can explain it is through an example:
So, lets say you only have 3 folders of images: A, B, and DCIM. In Gallery, you will see these folders listed in a 3D-like affect. They will appear with the folder name under the thumbnail(s) followed by the number of pictures in parenthesis (such as "A (10)").
Of all the folder thumbnails, you will see one that contains no name, but only a number within parenthesis. When I entered this album, I noticed some odd stuff. First, it contained a mix of black-only thumbnails (corrupted files) and images I recognized from my collection. Second, if you look at the details of ANY of the files in this gallery, they have no location, no height, and no width. Hesitantly, I decided to delete everything from this gallery (held my finger over the folder in Gallery and once it highlighted green, I tapped the trashcan icon). It didn't affect any of my pictures and the 3d Browser began working immediately!
I guess this collection was some sort of thumbnail collection or something. For whatever reason, it just accumulates waste over time and if an image no longer exists on the tablet, then the thumbnail appears as a corrupted file, which freaks the 3d Browser out.
I'm sorry if all that was a lot to read and absorb, but I think that doing one of these two things is the solution to this annoying issue.
