[Zope] ImportError with unlrelated and obsolete module

[Jay, Dylan]

I think some time in the past the transactions must have got tangled.
ZSQLMethods has nothing to do with PTKBase. When I try to access any
advanced tab from an ZQLMethod I get the following error. (PTKBase is no
longer installed and I have to need to install it)

<p>
 Error type:  ImportError<br>
 Error value: No module named PTKBase

Can I reinstall/clear/something ZQLMethods or something? I've had these kind
of problems before and they suck.
