Uninstalling Sophos Disk Encryption on a Mac

- tried to uninstall from /library/blaah ********.pkg

- starts unistaller but asks me to be sure that everything is decrypted (BTW never encrypted my HD) and ends my uninstallation screen.

- so, to be sure that I'm not a camel - and doing next step I'm now - encrypting the thing

- next step: decrypting it

- trying to launch uninstall from /library/blaah ********.pkg again

 - result is the same as in the beginning

How the hell I can get rid of your encryption software. I can see that library consists the shell file check_decrypted.sh as well and as far I understand this the reason why I cannot succeed with uninstallation.

I'm not techi at all so it may be stupid conclusion. Anyway - I need to get rid of the software from my MAC to be able to upgrade my Mac OSX.
