Ok, so here's what i've done up to now ( today)
Cleared out all instances of Launchbox and retroarch.
Disabled nvidia G-sync
Scanned the harddrives- fine
Installed a fresh launchbox
installed a fresh retroarch through launchbox before adding any roms as the retroarch installation progress would freeze at half way, if done after installing roms.
installed rom files, not folders with roms in them and copied the roms over to launchbox.
Tested roms and they boot as expected.
Tried SNES, Genesis, zx spectrum and PSX Roms all boot fine.
So at this point I'm still running as the free version.
The next step I add my license file it registered fine, then tried the roms again all, fine.
So next I restarted Launchbox to make sure it wasn't a fluke and all was still fine.
So now I closed launchbox and launched Big Box --- this is where the problems start.
I takes 7+ Minutes for Big Box to open up and when it does I cannot really do anything with it.
it doesn't see any controllers - tried to set them up in the options, but it freezes Big Box. I tried with and without DS4windows running.
Tried again waiting for it to load up then tried to install a theme, in goes through the install process, but then Big box freezes if I try to set the install theme as the default.
So then I have to force quit Big Box, which has an effect Launchbox, that now when I start up a rom, it take about 2 -3 mins to boot, it opens retroarch, but in this 2-3 min the retroarch icon in the taskbar is blank until the game finally loads.
My only option then is to remove the license file from launchbox and reboot my PC, to get them roms to launch at an expected speed.
So to me it looks like a problem with Big Box or my license file ( which I did download a fresh copy too- still no luck)
I've just installed the upadate that just came out and no change.
So basically I can only run it as a free verison ( my controller does work with the roms though), but if I sdd my license and try to run Big Box everything falls apart.
