I have tried all combinations of install to try to get FM5.5 to work on my server. Installing over FM5, installing FM5.5 after uninstalling FM5. re-insatlling FM5 with and without updaters, in "safe" and standard mode, with and without network connections. My only failsafe success has been installing FM5.5 on a PC on the network which is annoying because FM5 worked great form day one on my server and I hate giving up on a problem, but business comes first.
