I purchased SCAL in February and have been using it with my cricut without any problems. I just bought a gypsy and in order to use it I need to update my firmware. The version of my cricut is 2.34 and SCAL is 2. Can anyone tell me if I update my firmware will I lose the ability to use SCAL?
Thank you, your help is greatly apprecipated.

I updated mine last week and have had no problems. However I am going to be very careful in the future.
I am using Gypsy with Cricut Expression firmware 2.34 and SCAL2.
