print invoice error

I received the following error when I try to print out a customer receipt or invoice. It is the same error when I tried to setup my email account using gmail. I am using godaddy as the hosting.

Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

Please help.

hi, it's one of the functions that godaddy does not support because nop requires to be run in full trust

ARGH!!!!!!!!!!!
