I have bad news about Sony Clie's. Sony stopped production in North America. Read http://www.eweek.com/article2/0,1759,1605392,00.asp

Besides that, they shut off access to developer information which in my opinion was uncalled for. That's much like the child that gets upset and takes all the toys home.

Support has suffered too. You may want a PDA that is from a company that isn't leaving town.

In closing, read http://reviews.cnet.com/5208-6121-0.html?forumID=45&threadID=27291&messageID=307266 which was a repair of the MS-DOS prompt in XP. I'd help more but the error message isn't "quoted" in your post and I'd have to guess which one it was.
