Do you face this problem with a particular file or is it with every file ?
so far its just one file
So problem is limited to a single file.
Can post/mail your files?
Anything in particular you remember after changing which you started facing this problem?
How do I post the file? Nothing in particular, i just hadn't touched the file in a few days and then added a bunch of new animations/image files to it. I thought maybe it was just taking a long time to update the new changes but im not sure.
