Getting Error : Data at the root level is invalid

[Drigg]

This is happening when i open my eq2map program after it does it's short countdown.

it pops the error message:

Warning!

Unknown Error:

Data at the root level is invalid. Line 1, position 1.

This clicking on the ok box closes the application.
It worked fine last night (10-3-2012) and it is version 1.2.10.



Anyone else getting this? Any idea whats happened?
