I'm sure we would have had many more error reports regarding ULX if it weren't working since 9/11/15.
Though yours may not indeed be working, reasonably sure most likely still are and it is not a direct fault of our latest available code.
First and foremost, are you using our latest code from Github for Ulib, ulx and UTime?
It's updated almost monthly if not more (last ulx update was 26 days ago as of this posting)
What error are you getting in game and server console?
Can you use ulx menu command from game console?
What errors are occurring in console for UTime?
