A LOT of crashes when connecting!

[Whatever]

I started "playing" Project Reality today after couple months break ( because of often crashes when connecting ), somewhere before 20:00 my time.

1st Connection ~5m, "Corrupted network data".
2nd Connection ~5m, "Windows desktop".
3rd Connection ~5m, "PunkBuster hearbeat stopped".
4th Connection ~5m, "Lost key packets".

I succesfully joined one server.., but it was end of the round, so I played about 4-6 minutes. I counted how long does it take for me to connect. My watch shown me 5m 55 sec. Thats why I put ~5m.

Now its 21:08, I have taken my pills wich I believe will help me to relax ( no more Project Reality today ), otherwise.. I would need to do something stupid. Im not patient, and when Im angry.. Im dangerous. I already destroyed couple pairs of keyboards, speakers, headphones, and mouses.

I have Pentium 4 3.0 Ghz, 1.024 GB DDRAM, GeForce 9800 GT 512 MB, 2MB internet connection. Graphic in game is set to high, except antyalising ( off ), dynamic shadows ( off ), screen resolution is set to 1024 x 768.

When I played on my older graphic card GeForce 6600 GT 256 MB, I had the same problems. It doesnt really make any difference, how high, or how low my graphic settings are. I just dont know what to do.
