Xtrap issues

Hi,

For the past 3 days i've been faced with an issue with something called the XDVAnnn.sys file. it causes my comp to shut down with a fatal error. I've doen some research and all i've come up with is that this issue was last reported in 2010. I've been playing crossfire for the past 2 years and ive not experienced this error before. I've recently upgraded to WIN 7 (If that helps). If anyone has had this error and has found a workaround i would appreciate hearing about it.

Thanks in advance for the help!
