module/ps_wirepayment/validation error 500 after upgrade

[socomtactical]

at the moment no one can order from our site since we did the upgrade via 1 click update

 

I have tried roll back but it killed our website and messed up the database

 

module/ps_wirepayment/validation gives us Fatal error message as well as all other payment methods.

 

Any one got any ideas please?
