It seems your MySQL permissions got hosed. To fix:

- Start mysqld with --skip-grant-tables. This will give everyone 
permission to do everything, so make sure that nobody but you can 
access the MySQL server during this stage (i.e., disconnect the machine 
from the network).
- Add an entry to the appropriate table in the mysql database, so that 
root has useful privileges again.
- "flush privileges" or restart mysqld without --skip-grant-tables, so 
that permissions are enforced again.
- Test and make sure that the permissions work as you expect.
- Reconnect the box to the network.

However, this is not an RT-related problem, so I'd suggest turning to a 
MySQL mailing list if you need more help.

Messing with table files manually seems like a BadIdea[tm] to me, 
unless you like broken and inconsistent data.
