It sounds like mysql is pooched. You might try backing up your DB,
dump it and re-up with a fresh DB.
cd C:\Mysql\bin
mysqldump eq > OldDatabaseBackup.sql
(or substitute whatever you called your db)
Copy "yourdb.sql" to your C:\Mysql\bin directory.
Go to C:\Mysql\bin and open mysql.exe. Type:
drop database eq;
create database eq;
use eq;
source yourdb.sql
I should say somthing symbolic...
Run silent, run deep!!!
