Are you attempting to connect to a FileMaker 12 host?
Keep in mind the fileformat changed so you will only be able to connect to 12 server or 12 client as a host.
Hi Technology Dept:
Thanks for submitting your post.
The FileMaker Pro 9, 11/FileMaker Server 10 configuration works correctly because they share the same file format: .fp7.
FileMaker Server 12 introduced a new file format, .fmp12. Because of this, previous versions can not host or edit .fmp12 files and vice versa. So, in order for FileMaker Pro 12 to see files in Open Remote, the files must be in .fmp12 format and hosted by FileMaker Pro 12 or FileMaker Server 12.
Hope this helps.
Which braniac programmer decided to do that?...because now we can't use FMP 12 because of some other machines running FM Pro 11!
WOW, Really, I just ran into this myself.... The fact that they decided to change file formats doen't upset me.. i assume you have to do that every once in a while to add features... but They should have A big BANNER plastered across the FM 12 page when you buy the upgrade.... that "ALL YOUR OLD DATABASES & HOSTED SERVERS WON"T WORK !!! " if you update .... WTF ??
