Taking forever to load a model??

[Rampage0007]

I had a .mdl I was working on and while I had a section highlighted, accidentally pressed delete instead of Page Down. whoops! AM locked up (froze) on me like it had hung, so I closed it and restarted the program. However, now it takes it almost an hour to open that one particular model. I am using v.12 Can anyone offer me any insight on how to fix this problem?? Thanks!!

You could open it in notepad and look at the code. Perhaps there are thousands of lines of duplicated code which sometimes can happen.
