I have removed your images. As mentioned above, these contain personal information.
The error you're experiencing is unfortunately due to a "crashed" database table.
It is important to understand that while there are several reasons that a table crash might occur, it is always caused by the server. For example it can be caused by the server being improperly shut down or restarted, hard disk drive failure/errors, improper repair attempts on a database, etc. The Invision Community Suite cannot, in itself, cause a table to crash.
Repairing a crashed table is a simple process, however we strongly recommend that you contact your hosting provider and ask them to repair it. If we were to attempt a repair, or you were to attempt a repair yourself, it could cause further complications, and it is important regardless to report the issue to your hosting provider so that they can investigate and resolve any server issues which might cause the problem to happen again.
We hope you are able to quickly resolve this with your hosting provider.
