Hi, I have lately re-installed my computer with XP Pro SP3 due to a virus issue. My MasterCAM v9.1 SP2 seems to work until I install Comodo Firewall Pro. It seems it has block my License Manager from starting up. I have tried to uninstall it but I cannot locate it under the “Add / Remove Programs” or the “Uninstall” under Start → All Programs. Please kindly advise what I should do.
