>I´m sorry, but I´m not feeling better now. Upgrades are always dangerous. I could not find instructions on how to upgrade from 3.02 to 4.01. Where is it ?>

My recommendation of setting the include file has nothing to do with the upgrade from 3.02 to 4.01...for some reason your class library lost its reference to the Include file and it simply needed to be respecified.

The instructions for upgrading from one version of the Framework to another are always listed in the "What's New Guide".
