Description of the issue

Help! I'm I file maker 9 user/developer but only develop for my own use. I have had 4 new machines installed at my office and I thought I'd get the new version of FM installed so my I.T guys installed FM 12 trial versions on the new machines, I'm developing a new solution at the moment so don't need the full versions everywhere just yet.
we are peer to peer and whilst I open the solution on one pc, therefore I am hosting, I cant see it to open it using "open remote" I can see the PC (ip address) but not the FM database. if I try to just open it in the normal way its says this file is in use; because its open on the host. I have bonjour and both the file and FM 12 trials are all setup for sharing.

any ideas anyone, I'm lost!
