The update should not have made any such changes. Are these buttons in your tool bar or buttons on your layout?
To revert to v1 would require re-installing FileMaker 12 from the original installer. Did you keep a copy of the installer? If so, you can uninstall and re-install.
Ya, those buttons are on my tool bar. I also saw that under the "Records" drop down list, there was an option that said "@@" i clicked it to see what it was and a window popped up saying "Are you sure you want to delete all records?" i clicked no. It wasnt every button but most buttons seemed to have been re-labeled. I tried to uninstall the V2, but i accidently uninstalled the whole program. So as of now im trying to find our disk to re-install Fm PRO.
If all else fails, pick up the phone and contact customer service with proof of purchase. I can't promise, but believe that they can then set you up with a v1 download link. They may also suggest a v2 download (not the updater) and it is probably your best bet to get back up and running.
Alright, ill try that.
