Problem adding a file to existing RAR archive in TC UP 3.0

[[HUN]Peti]

First of all, wow, really it is a cool pack, but not Ultimate; it's ULTIMA.
The guy who creates it, uses this name, but don't worry, people call it Ultra Prime as well. (Sorry if I'm mistaking, but I think Ultimate (with capital U) means you think that's the name, if you don't, then sorry)

I think: if you can pack new archives with that wcx (compressor) plugin, then plugin itself is all right, just doesn't support what you want to do. I've noticed that my TC UP shows WinRAR's screen while using rar compression, so it's possible that you need WinRAR to work perfectly.
