Weird Error Message .... CAN ANYONE HELP??????

[Atalanta]

Have FileMaker Pro files open on one Mac and want to log in as a guest from another Mac. Launch FMP on second Mac, FILE - OPEN - HOSTS and get the following message "FileMaker cannot host or be a guest of a file because ." Really, it doesn't say WHY! Any suggestions???

Host: iMac running 10.2.1

FileMaker Pro 5.5v2

Files are set to Multi User

Network is TCP/IP

Guest: eMac running 10.2.3

FileMaker Pro 5.5v2

Network is TCP/IP - can log onto host as a guest from the Finder

Ran disk Utility and repaired permissions between tries

Threw away FMP preferences to see if that would help, no.

Thank you very much for your help!

Not yet. Normally that would be the first thing I would do but I also wanted to see if anyone had other suggestions.

Thanks though!
