CC module prevents users from editing profile

I enabled the Creative Commons module last night and everything seemed to be working great. Nodes were getting tagged perfectly. Then a user reported that he could not edit his profile, and I verified that editing your user profile throws this error:

Fatal error: Call to undefined function: save() in /home/gdelisle/public_html/modules/creativecommons/creativecommons.module on line 754

Line 754 is this function:
function creativecommons_save($node) {
$node->cc->nid = $node->nid;
$node->cc->save();
}
(specifically, line 754 is $node->cc->save();)

Having the module enabled in any way produces this bug, which discards any changes to user profiles. I assume that it also prevents new users from joining the site, though I haven't tested that. I'm using CivicSpace 0.8.0.3, which may differ slightly from Drupal 4.5.2 in the way it handles profiles; I'll be glad to send you whatever info you need. I think the main difference is in the CS Contact module, though disabling Creative Commons for Contact nodes did not prevent the bug either.
