comodo antivirus engine not initialized on Vista

I have vista 64bit sp1 with comodo internet security
after the last update I got an error form the antivirus : engine not initialized
I tried the solution that was given in the forum but I didn’t found any bases.cav file
what can I do ?

Please Make sure to disable Real-time scanner and Automatic AV upddates until doing the following.

Download it from rename the file to bases.cav and copy the file to *C:\Program files\Comodo\Comodo Internet Security\Scanners and restart your system…

*Location may vary depends on your Installation directory.


Works fine also fixed the freezing of the pc when pausing manual scan in progress.
