Zandronum Crashes when joining netgames

Hey guys
So as the title says Zandronum Crashes when joining netgames,i used to play it fine with no problems but now i can't ,all i can read is "Requesting Snapshot" on Console after joining netgames and the game is completely frozen .. i updated the graphics card and DirectX Version but i still can't .
Device informations :
Graphics Card : 64mb
RAM : 512mb
Operating System : Windows XP Service Pack 3
DirectX Version : 9.0c
i tried to :
* Reinstall the game
* Change game path
* Removed all Pwads and Re-downloaded them using Doomseeker
The game runs fine before joining netgames,and then it crashes when i do .. ,is there anyway to fix this ..??

I would recommend Internet Doom Explorer

Doomseeker is very glitchy, and Internet Doom Explorer has support for 3 different ports.

Just uncheck all but Zandronum.

EDIT: DOOMSEEKER.

I beg to differ.
It runs pretty swell.

However, it's the only source port I've used, so what do I know?

Oops, I meant Doomseeker.

Didn't you know,i'm using doomseeker for Zandronum,it doesn't support any other Sourceports..it's ok i just noticed that i installed a new MIDI Device,i removed it and everything is alright now .. thanks for helping .. your methods will be useful for future Problems
