Hey man, chill.
I have been using C3 for a year and I would advise if you are using C3 to always use the latest beta
it will usually have the least problems, and any major problems are always fixed very quickly
up until a few weeks ago I would advise develop using C3 but with C2 runtime
but from this week I would say it is pretty safe to also start using C3 run-time full time.
C3 is excellent software, you will see.
also, it may not be obvious right now, but there is a really good and helpful community lurking in the shadows.....
