Just tried to start Sealion MP but got following: The scripts or other data ....your opponent do not match yours...etc anyone help with this?

Yes, i've just had exactly the same problem with a Sealion scenario.
No idea why!
They recommend me to abandon the game

It is designed to find data which has been tinkered with by players which could cause issues in the game. There do, however, seem to be the very rare false positives sometimes.
