Crashing on joining HL2-RP

[Novexus The Grey]

So i download the cache. The intro sound thing. Then it goes to sending client info. Stays there for a while.
Moves up to the almost last bar.. then HL2 crashes giving the error
"HL2.EXE Has stopped responding..." I can join other servers perfectly fine. Plus this is the first time joining
your server. If you could help me out id appreciate it.

Load up singleplayer first and then join.
