I too bought a CRICUT when they first came out. It had to be ordered from the USA. It drove me mad! 😡I tried to link it to my PC and had all sorts of problems and I'm quite tech savvy. I haven't used it in three years.
When I did a lot of crafting , scrapbooks, cards, wedding stationery I joined a scrapbook forum called ukscrappers and they had a very well used cricut section. It might be worthwhile you joining that for the answers to your questions . Sorry I can't help but I'm so out of touch with it all now.
