Question: Technical assistance, integral returns error when VectorCalculus is loaded

Hi.

I´m making a work sheet where I use the VectorCalculus package to evaluate surface of a plane.

When I try to evaluate a regular tripple integral after loading the VectorCalculus package I get the following error:

Error, (in VectorCalculus:-int) the domain must be an equation with a list of names on the left hand side

If I use the task menu to remove the package it works just fine, however I want it all as executable syntax within my worksheet so I tried "unwith(VectorCalculus)" but the package wont be removed by using this command.

How can I go about solving this issue?
