It happened some time also to me.
Under Windows 7 I got a similar message, after some experiments I realized that it happens when I shut off Windows AND Guide is minimized. At the following start up I get the message.
If Guide is on the screen or close at all no problems.
At the beginning I simply replaced ALL files in the Guide folder, after a while I realized that it is enough to keep a separate copy of the file STARTUP.MAR and replace only that.
Bill, what do you think about?
