Cant view payment module in admin

When i log into the admin centre of my website and press the payment from extensions-payments, i just get a blank white screen

this is the link im getting.. http://wehaveanysticker.com/admin/index ... en=xxxxxxx

also there is nothing in the source? help

thanks

if you have added any payment module extension other than the default, then that is most likely the problem

If this is a default install, upload the admin files again

ive not added any 3rd party modules

ive also uploaded the admin files again with no luck..

ive got vqmod installed but tried disabling that temp, also tried the default theme with no luck..

any more help?

thanks
