Some error messages will provide information on how to correct a problem.  For example, if you enter an instrument name that already exists in the system, you will be asked to amend the name.  Other times an error message appears more technical and does not give you a clear indication of what to do.  In these rare cases, copy the error message, note where you are in the system (what screen, what you were trying to do) and the date/time you received the error.  Then, contact help@assessmentcenter.net with this information and we will try and resolve the problem.
