Custom Dimentions, Error: All Custom Dimensions for website 2 in scope 'action' are already used

Hi, I have just installed Custom Dimentions plugin and when I try to make a new Action Dimention I get the error “All Custom Dimensions for website 2 in scope ‘action’ are already used.”

I think this is strange becous this is my first time making one and the default number of dimentions is 5.

Update: I see now that text on Action Dimentions button reads “CONFIGURE A NEW DIMENSION (0 OF 0 DIMENTIONS LEFT)”. Is the database stil working on adding the dimentions tables and cells? Or what is happening?

Any idées?
