Updated from 0.35 to 0.39.4 and after some days working fine my PAR2 tab was somehow not working anymore.
A couple of files just stuck in there, cleanup and manuel deleting was not working after closing alt.binz these files just showed up again with a green symbol.
I just deleted the par2info.abz file (size 28KB) after alt.binz reboot everything works perfect again !
Thanks guys
