Guess I'll just have to only use it online since not being able to preview offline kinda makes the whole thing unusable. It works fine offline until I try to preview, then nothing.
I'll be having to find another thing such as Unity though when my projects in it are all done because I don't feel like paying a subscription for something where I may not have reliable access to the internet which then makes it not work at all.
This kinda makes me sad because C3 is actually a really great thing, but oh well I guess.
