I downloaded the free trial version of Cricut Design Studio only to get the firmware update. My SCAL is working great, so I'm wondering, can I now uninstall the DS? I am not going to use it, but I want to make sure it won't mess anything up if I remove it. TIA!

I'm trying to delete some fonts I won't use, and I'm wondering why some of my fonts have an @ sign before the name of the font. For example, I have @Batang, @Dotum, and then I have Batang and Dotum without the sign. They look like the same font. Can I delete the ones with the @ sign?
