Never report to any mod author that 'it doesn't work', because, well, hundreds of people (and, since ULX is 5+ years old, thousands?) have used ULX.
Provide details. Always.
Did you download BOTH svn of ULib and ULX. SVN ULib is required for SVN ULX.
You mentioned in another post using the 'release' version downloaded from here.
Before installing SVN, did you try removing the old files first?
Did you follow/read/learn from the readme files included with both?
(See /addons/ULib/ and /addons/ULX/, both have readme files)
After placing them on your server, while starting up your server, ULib (and ULX) will attempt to show startup messages.
They will also provide errors if they can't.
Did ULib and ULX load on your server? (Your server console will show them loading).
What isn't working?
What are you trying to do?
What are you expecting ULX to do for you without your intervention?
Was the alignment of the planets in synchronization with capricorn?
Was it a full moon?
Did you sneeze when you installed them?
"It doesn't work" is no help to us to help you.
