I like the new CbB, and when it's running I can't say that I've run into any bugs or crashes just yet.
But when it comes time to installing them, I get all kinds of bugs. Hanging installation progress bars, files that don't look like they're downloading even though they really are, etc. There are some work-arounds (which is the only reason why I'm able to run the program in the first place), but I've noticed that for both CbB and Bandlab Assistant, installing is NEVER a simple click-and-it's-installed process.
