Cannot reinstall Comodo firewall v3

Using latest version on my laptop using XP SP2, been using it without problems, but today, all of a sudden it crashed on startup saying possible comodo bug and got a window for me to choose to send the error file back to comodo, every bootup, i will get this error and comodo will not start at all. Tried uninstall it, problem again, error again and uninstallation failed,tried to uninstall it in safe mode, done.
Next i download cfp from comodo and install the firewall again, error encountered cannot install.Trid to install in safe mode, installation went ok but when startup in normal window mode, same startup error again. I’m at a loss currently. i really like this firewall and i want to make it work again as b4, can anyone help me to solve this problems. Thanks
