Your report is a little bit like "My car is broken and a yellow light blinks."
I guess that the error 1146 you are mentioned is an mysql error 1146 that means that a table has not been found. I do not know which table nor which fields are missing.
Further, since my crystal ball is broken, I can only guess that you have updated from a very old version of uddeIM to a newer one that requires additional fields or tables, e.g. from a uddeIM version that does not support attachments to a version that supports attachments and so requires a database update. In that case check the enclosed README how to upgrade the tables and add the required fields (btw the last required database update was years ago).
