Answer 1

Did you try the solution in this TechNet post ?

Also try giving the APP Pool account access to the c:\windows\temp directory.

Answer 2

SharePoint does many things while saving the site as template; its a long and complex operation. As Deepu suggested, check the access to the temp directory. But you already same operation for other web is working fine (assuming you are trying to save from same machine and save to same directory), so that possibility can be eliminated.

In almost all situations an actual exception message would be logged in ULS logs before InvalidOperationException is thrown.

I suggest you to go to Diagnostic Logging in central admin and enable Verbose trace logging for "SharePoint Foundation -> General" and then watch (I recommend using ULS Viewer Tool) what's going on after you try to save as template and before the error appears.
