I noticed this myself recently. It's an issue with readcharmmtop in Topotools, not with CGenFF specifically (in this case - CGenFF still causes other issues in VMD at the moment). If a comment has a ". in it, it causes an error. I fixed the plugin to not get caught on this, but in the short term one can just remove the offending ". from the topology file.
Although Paratool is not under active development (and was almost too ambitious to begin with, honestly), "something" to help with parametrization is coming eventually...
