I had to use a screw driver wedged underneath to get some leverage and SLOWLY AND VERY CAREFULLY peel it off.
It was a daunting task and was afraid of stuffing up my board, but managed it in the end.
Main thing I can recommend is trying to get one corner off and peel it off rather than trying to pull it straigth off (cause it jsut won't come off like that)
They really should have used something a little less efficient at sticking. Cause once everything put together not like it was going to come off anyway.
Edit: I take no responsibility for damage incurred if you follow my suggestion. Its risky, but th eonly way I could find...
