Received "Unknown Error" message on opening

Hello All, Today when I clicked on the EQ2MAP Updater button the map updater started to work, then ...

Received "Unknown Error:
Data at the root level is invalid. Line 2, position 1."

The MAP Updater was working fine last week. Anyone else receiving this message? Is there a patch available to correct it?

Thanks for any assistance!
