lossing skin and sound

I've been using TLB for sometime now and its a great program and i've never had any problems with it, but today i upgraded from 512MB to 1024MB of ram and now when i load up BF1942(this is the only games i've tested so far) and join a game then exit out of the game i lose the skin(it gos to the windows classic style) on the taskbar and i lose sound(by this, my computer dosen't even show that i have a sound card) and have to restart to fix it, i have the newest version, can someone please tell me if theres away fix this? i know its a bug with TLB, because i tested without TLB on and i didn't have any problems, i love TLB and i dont want to have to stop using it because of this bug
