There's a bug in the 3.00.2p release that initializes things in an order that Windows 2003 doesn't like. This occurs only on Windows 2003 (not 2000 or XP).

The fix for this is in the beta (http://www.pingplotterpro.com/beta.html) - look at the release notes for beta 4 to see where the problem was fixed. We're just in the final throws of building a new beta release (it will be ready sometime in the next few hours), but the particular problem you're talking about is fixed in the current beta.

Let us know if there's anything else we can do to help. Sorry about the problems!
