Susan:
We have discouvered that our solution created more problems than it fixed and we have restored our DataCare from a pre-cleanup backup. The problems you describe are only a small portion of the total issues incountered with the clean re-install.
DataCare works fine with the error, it's just an extra button to click on when you exit DataCare. For that reason I will leave the problem for Softrak to deal with but as they can't replicate the problem it may be some time before it gets resolved.
