Failure at Update stage

[Omie]

New Install, I'm stuck -- I get the following messages

Warning: Unknown Error - Invalid Signature

at EQ2MAPUpdater.MainWindow.DownloadUpdates()The settings property 'MAPFilesURL' was not found.

Errors ocurred during update, EQ2map may not work, do you still want to run EQ2?

Any Ideas? EQ still works, but the map program does not.
