I crash 2-4 times an hour on Prophecy of the Five. Started out just on WZ's but lately I have stopped WZ due to disconnect and just lvl lowbies and now it happens there as well. Every time I crash it says error 9000 and takes me to log in screen. I have replaced the modem since i thought it was a ISP issue.. still crashes. I don't lose internet since people on Mumble ask me where i went since i am the healer.
Computer is a 3.1 quad core with 12 Gb of memory, nvida graphics with 1Gb of memory.
Speedtest.net says i have good download and upload.
Only thing affected is my SWtoR.
My World of Warcraft never crashes.
First suggestion is to turn off mumble and see if the crashes continue.
