I said unsupported, but ...
I think I see what the problem is there, you've obviously lost and gone into negative but the vcash column is unsigned. You need to make teh vbookie_cash column on the user table signed. Make it a bigint(20) and you should have plenty of scope for growth ...?
SQL Command:
Code:
ALTER TABLE `user` CHANGE `vbookie_cash` `vbookie_cash` BIGINT( 20 ) NULL DEFAULT '500'
or do it via PhpMyAdmin
