I decided to upgrade to WM5 and am trying the radio stack but it's just not happening. I'm using XP SP2 with all the latest patched, Samsung drivers installed and Device Manager sees it as Com3: When I run the PST, I just get stuck at Download Start. I've tried other com ports and get a "request copy error" instead.

Is the update supposed to take forever, or should it be pretty fast after Download Start comes up?
