Macintosh FileMaker 6.0v4 all of a sudden not working with Server 5.5
We have 6 Macintosh OS 10.4.11 and 6 Windows XP computers all running FileMaker 6.0v4.
On March 18, 2010 every Macintosh except one using FileMaker Developer 6 stopped working with the Server 5.5
When the client on the Macs is launched and we try to open the remote connection to the server, we get a message "Application not responding"
We have tried a lot of simple fixes, reboot the computers, reinstall the program, but have had no luck with the Macintosh clients using 6.0v4
All of the Windows XP computers using FileMaker 6 are working, as is the Mac using FileMaker Developer 6.
Please any suggestions to solve this would be greatly appreciated. Thank You.
