LASR software crashed in the middle of use and would not restart with some generic popup error.
- Rebooted: Same thing
- Uninstalled & Reinstalled product: Same thing
- Uninstalled, delted documents/lasr and checked regisgry (nothing there) then reinstalled: Same thing
The eventual fix was removing the c:\username\appdata\local\Laser_Team\Laser.exe_SID\version\ and deleting the user.config. you can, of course delete the whole Laser_Team folder and it will rebuild on next launch. Luckily I didn't delete the documents/laser folder but renamed it so I copied it back and I'm back in business.
NOTE the appdata is a hidden folder so you have to type it in. Alternatively, you can "run" %appdata% and it will tak you to your appdata/roaming where you can back up one level and see appdata/local
Hope this helps someone else.
