Why Cubicost TBQ crashed immediately upon log in?
This is most likely due to corrupted installation of Cubicost TBQ. Reinstallation of same Cubicost TBQ version should solve the crash issue.
This can also be caused by 3rd party Antivirus software which quarantined or removed some Cubicost TBQ program files. We recommend Windows 10 built-in Windows Defender.
