I'm having the same problem. Anyone have an answer?
After some tests and trial and error, I figured out the solution. When you're installing the server piece, you have to move the date back to 2009. I guess the certificate the filemaker attached to their program expired in 2010 so even though it installs, it fails running. When the date is moved back, then certificate is still valid and thus the install and services work perfect. After the install, move the date back and you should be good to go.
Thank you so much for figuring that out and sharing it, Wissam. Best wishes.
