So, I messed with my firewall a bit, and yes, PLauncher is the grey box that opens that does something before the actual Lunia patcher opens. So in theory bypassing that with the RUNGAME in the LuniaClient.exe shortcut should work. Or, since I assume it has to do with ijji's plugin for whatever browser you're using, reinstalling that should work.
That's all just for future reference. Good luck with your computer repair.
