Switching between Filemaker 9 & 11 causing database problems in Filemaker 11
Operating system version
Mac OS 10.5.8
Description of the issue
We have two people working on the same database, however one person has Filemaker Pro 9 while the other has Filemaker Pro 11. The database works well in Filemaker 9, however once we switch over to Filemaker 11 certain fields don't always appear and are difficult to recover, also crashes periodically. Specifically our unique number field for our records keeps disappearing. Are these two versions of Filemaker not compatible? Are there any easy fixes for this issue?
