title: Error 5080: Form Transaction Registration failed
body: <p>I'm getting this generic error whenever I redirect to the payment gateway. I have two SagePay customer accounts available - I can make a test payment using the first account's credentials just fine, but I'm getting 5080 with the second one. </p>
  
  <p>They are both sending the same raw crypt string except for VendorTxCode, Amount, and Description.</p>
  
  <pre><code>VendorTxCode=111_7_10_2&amp;Amount=1.00&amp;Currency=GBP&amp;Description=OnlinePayment:WebPaymentID:2&amp;SuccessURL=http://localhost:50186/Payment/ProcessRedirectResponse?TokenID=5&amp;StepID=12&amp;FailureURL=http://localhost:50186/Payment/ProcessRedirectResponse?TokenID=5&amp;StepID=12&amp;CustomerName=_Test&amp;BillingSurname=_Test&amp;BillingFirstnames=Tester&amp;BillingAddress1=Address&amp;BillingCity=City&amp;BillingPostCode=PostCode&amp;BillingCountry=GB&amp;DeliverySurname=_Test&amp;DeliveryFirstnames=Tester&amp;DeliveryAddress1=Address&amp;DeliveryCity=City&amp;DeliveryPostCode=PostCode&amp;DeliveryCountry=GB
  </code></pre>
  
  <p>My first thought is that I may have the wrong encryption password, but I copied the Vendor Name and Encryption Password directly from MySagePay Test. </p>
  
  <p>Is there anything I missed?</p>
