Well you are only the third person ever to report that Microsoft Visual C++ Runtime Library error.
In the other two cases, one image was corrupted, causing the file, not the program to be corrupted.
No known reason for that image to corrupt.
You can develop file corruptions for many reasons: too many images on a page, too many images in the file, too many pages in the file, bad anchor names, bad code inserted into a web page (incomplete, missing characters), file is too large for full compiling. Sometimes things run smoothly till you pile just one too many items and then it topples over.
Please test your CSB.
Go into CSB and create a simple one/two page website with any image, but not the one that has caused a problem.
Save that file to your desktop or my docs.
It should work fine for you.
This will show you that the program itself IS working.
Do you have a previous version of the tlx design file that you can go to and update?
If you do not have a backup to work with, you will have to open the file, put it on your home page, the right click the offending page in the map and delete/cut it out.
File SAVE AS and give it a new name.
Then rebuild the page that caused a problem
Fastest way is to open Internet Explorer and copy/paste.
