Today out of the blue mysql just stops running for some reason. Here is the LOG any ideas? Sorry if it's obvious i'm new to this. Thanks

Have a backup of your database? Looks like some of the data may have corrupted. I recommend not stopping MySQL with the control panel, rather use mysqladmin command line to do a clean shutdown. Can also happen if your computer is shut down while server is running.

comment out or delete innodb_additional_mem_pool_size on your my.ini configuration for mysql. a missing mysql user table can easily be solved though phpmyadmin if you have one installed.
