I recently upgraded to 12.1 from 11.4 (64 bit) wherein Quanta + was working fine. After the upgrade, when I attempt to activate Quanta + it tries to come up, but it doesn't. I am using the KDE 3.5.10-35.1.2 web development suite. Could you please give me some clues as to what is ailing this app? Thanks in advance.

P.S. I tried my other fav apps which are still working.
