Craft Edge

I have scal2 + cricut personal machine. If I download the "Craftroom" program from cricut, will I lose the use of scal2 and what will Craftroom do?

I am not sure what that software does...you could check with the maker of the program.
As to d/l it...I don't think it will cause any problems with scal, unless you would change firmware on the cutter.

There might be more info about all this in 'search'.

I think I heard you can have both of them and use them both, just can't be using both of them at the same time.
