# What should I do if an error message appears when starting Revit?

If the error message is from the BIM&CO plugin, we advise that you close Revit and restart it.

If the problem persists, restart your computer.

If this doesn’t work, uninstall the BIM&CO plugin and reinstall it by going to [this link](https://www.bimandco.com/en/bimandco-plugins).

If the error message continues to show, our support teams are on hand to help you solve the problem, either through the BIM&CO online chat function, or by contacting us at [this link](https://www.bimandco.com/en/contact).
