I downloaded a free no-strings-attached sample file from a great FBA platinum company. When I try and open it in the latest version of FMPA15 (220.127.116.110) I get an error message of:
"FileName.fmp12" was created by version 16.0 of FileMaker and cannot be opened by this version.
Use version 16.0 to view this file.
The discussion of FileMaker version compatibility here (FileMaker Server 16 Technical Specifications | FileMaker ) seems to indicate there shouldn't be any problem. This happens whether the file is local to my machine or whether I upload it to my development FMS (18.104.22.168) server.
I'm sure I'm overlooking something but ...
