Ok, you've lost me.
Did you _just_ buy Gmod for $10 (perhaps with another package/game for more)?
The 'new' Gmod using the new engine costs money.
If you _just_ bought the game and are trying to run old non-cost Gmod addons, then no, they won't work

What versions of ULX and ULib do you have.
Look at the server gmod/addons/ULib/Info.txt and gmod/addons/ULX/info.txt and tell us.
