Unable to send a project/survey to an existing Asbestos Tracker database - why not?

The problem is that Tracker thinks that you have already sent the project over to the client's Asbestos Tracker system.

Check for a folder with the name of the project number in

{your Tracker drive letter}:\Asbestos Tracker\{Client}\HTML\Project_Files\{Project Number}

If the folder exists, delete (or rename) it and try again.
