user registration problem

Fatal error:
* A required field called userid is missing or has an invalid value.
Unable to proceed with save while $errors array is not empty in class vb_datamanager_user in /includes/class_dm.php on line 763

how can i solve this problem

I fixed that error but now it has been given following error. Although last member ID number(user ID) is 215980, it is giving new user id as 4294967295 and at the end of the registering it gives sql error.

When I try to add new user from admin panel then it gives following error.

A required field called userid is missing or has an invalid value.

That's not good. For some reason you have maxed out the available userids. This is something that only happens from a bad plugin or hack.

Do you have a recent backup of your database?

It gives same error with the last taken dbase

Then unfortunately that database was damaged too. I honestly don't know if this is fixable without losing a lot of data, but please fill out a support ticket at:
