Error in Customers Details in Admin Section

When I click on the Customers page in Admin, I get this error message at the top of the screen.

Customers Search:

Warning: array_merge() [function.array-merge]: Argument #1 is not an array in C:\inetpub\vhosts\ipod-incar.co.uk\httpdocs\admin\customers.php on line 1099

Warning: array_merge() [function.array-merge]: Argument #2 is not an array in C:\inetpub\vhosts\ipod-incar.co.uk\httpdocs\admin\customers.php on line 1101

Warning: reset() [function.reset]: Passed variable is not an array or object in C:\inetpub\vhosts\ipod-incar.co.uk\httpdocs\admin\includes\classes\object_info.php on line 29

Warning: Variable passed to each() is not an array or object in C:\inetpub\vhosts\ipod-incar.co.uk\httpdocs\admin\includes\classes\object_info.php on line 30

I have customers in there, as the name is showing, but when I go into the specific customer, all of the fields are blank. Even if I go in and fill them in manually, they are still blank after clicking update, and the error message is still there.

Can anyone help?

Problem solved, was a rogue glitchy customer account, wouldnt delete from admin, so had to delete from database and all fine.
