Hi, I was having trouble with my computer freezing up so I went to Hardware and then to Device manager. I clicked on show hidden files and I had a exclamation point next to mdmxsdk. So when i got on the properties it showed not available, no driver installed so when I went to Help and Support it said try uninstalling it and then reinstall it. Well. I uninstalled but have no idea what it is or how to reinstall. Now on the device manager I have a exclamation point beside the Streamdispatcher. What have I done? And how do i fix it? Also call me stupid but what does mdmxsdk mean?:I forgot to say I use Windows XP Home edition. Thank you
