i just installed the newest version of lmms, and something's very wrong with the piano roll.

i have windows 7.
on installation, i set the folder path so that it would be the folder of my older lmms.
(default path was LMMS 4.0.1.5 and i changed that to LMMS)
i didn't explicitly uninstall my older version.
what shouldi do?
