Grabbed the SE5a, but when I tried to buy the Pfalz my bank declined the purchase.

I appreciate them looking out for my money as they were concerned about the foreign transaction apparently. I need to call them and try again.
edit - got it. I called my bank and they traced the error to the neoqb server. The bank didn't decline anything. I ran it through a second time and it went through without a hitch.
