what version of windows are you using? I would also google that error code and see what you can find out about it, don't think it matters if it's for a different phone as long as it's for an android phone, looks to be some type of htc sync problem from the quick search i did, or a windows 7 issue. I would also restart the computer after you mess with htc sync, like i said i believe you have to uninstall it and you should reboot the computer after that.
***EDIT***
did a quick search on this site and here was one thread that said to use the s-on and use a stock image, here's the link:
