CGEtension Module installation Error

[Peciura]

Update to CMSms 1.8.2. Install CGExtensions over ftp.

I've had this problem many times while upgrading my CMSMS version or simply installing/upgrading that module.

I found importing the .xml file for the module sometimes helps, or like Peciura suggested (make sure you're running the lastest CMSMS version), ftp the module files and directories over to the /module folder and then install the module through the admin console.

Good luck!
