How do you remove the fuse box cover?

I think I have blown the fuse for the my CD/Radio but I can not work out how to take off the clear plastic fuse box cover.
Can someone PLEASE HELP?
This is sooooooo frustrating.:aargh4:

Thanks

I finally managed to get someone in a VW servicing garage to show me.
Basically it requires brute strength and your fears putting to one side.
Try to pull upwards from a bottom corner of the cover and it will eventually come off its catch.
The a bit of wiggling will get the other end off.
