So I've had this problem for a while.

Trying to use paysafecards to buy DDO STORE points, It all goes well until i press the 'place order now XX.XX button' then its completely random when it crashes if at all, now im stuck on crashing while pressing 'add more codes' button. Içm using windows 7, after the crash i get window which says that DDO client has stopped responding/working (etc) and other , giving me 2 options 'search for solution and close the program(which does not search for the solution even if i press it) or just close the program.
Any ideas how to stop crashing?
