Some people have problems with their databases in Snow Leopard.
Filemaker does not support the combination.
Does Filemaker crash on opening or when you open your database?
Can you make a new database with some fields, and reopen it?
Download the FM ver10 trial and test the database.
Thank you so much for your response.
I can not open any existing or new files - crashes as soon as I open anything.
I will try the V10 trial and fingers crossed it works.
Thank you for your posts.
I have installed FileMaker Pro 8.5 on a Snow Leopard machine, and it appears to work fine. I am able to open files, run finds and sorts, etc. There are some printing issues that are documented at:
If you updated to Snow Leopard after FileMaker Pro 8.5 was already installed, then I would uninstall and reinstall FileMaker Pro 8.5.
I had exactly the same problem as you, ie Filemaker closed down whenever I tried to open any file (Filemaker 8.5, Snow Leopard). Happily, I've found a solution!
I was using Filemaker 8.5.0. By uploading to Filemaker 8.5v2, it solved the problem. I can now open files and work normally.
The download is here:
Hope this helps!
