RB 2.2.4 will not start properly

Hi.

i've been using RB for a couple of years, with no problems.

Suddenly it needs a LIcense Key. It is already activated, but now it woundt don it anymore.

I don't have the original cd anymore, so i cant get the license key.

I am in at bit of a hurry, becourse i am going to work, in a couple of hours .

Using RB 2.2.4. Win 7 64bit

What to do?

Kind regards

David
