Remove module CGExtensions

[seh87]

I attempted to install CGExtensions 1.17.2 and completely broke my admin panel. I have done some reading on the issue and believe my problem may have come from the version of PHP that is installed.  My installation is on a university server and I believe they are running some version of PHP pre-5.  That isn't so much what my concern is currently.  I just want to get rid of CGExtensions.  However, when I go to the Modules page, all I see is this error:

Parse error: parse error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /export/htdocs/Dept/Org/Student/SGA/cms/modules/CGExtensions/CGExtensions.module.php on line 47

Most of the other admin pages display some information, but look as though the CSS was stripped away.

I have also tried to delete the directory via FTP, but it fails from not having the correct permissions. When I try to CHMOD that fails as well. I saw elsewhere that I may need to delete other modules that depend on CGExtensions, I deleted a couple of things, but none of that seems to have made a difference and I'm not sure if there is anything else that is dependent on it - I don't want to delete the wrong things.

Where to now?

Thanks.

Where to now?

Last night's backup? 

Failing that, get someone to log in as root and CHOWN the CGExtensions directory to your user. Then try to remove it.

Thanks.
I just reinstalled CMS in a different sub-directory, minus overwriting the tables. Pretty much solved things other than I had to fix some links. I'll do clean up later, I just needed things back up and running pretty quickly.
And I'll be sure to read prereqs next time!
