Testing direct version

Hi Richard,

Ive had a chance to test re the direct setup, I used . in the fields for the encryption key and test mode encryption key. Im using a proper sagepay account set to test mode and override card dets for testing. I seem to be getting errors when trying to clear line items off the cart page - Error
The website encountered an unexpected error. Please try again later. Checked the log and got this DatabaseTransactionOutOfOrderException: in DatabaseConnection->rollback() (line 1058 of /mnt/web/www/sites/hswalsh/html/includes/database/database.inc). - which may not be connected at all? Same issue if I try and go past the checkout screen.

Just noticed you have updated the module so I'll update. Im testing by switching off the previous sagepay direct module and switching yours on - not sure if this is the best way or if Im better off uninstalling the old one?

Latest Drupal core and commerce 1.5

Thx - Kevin

EDIT:
Ive updated to latest dev and cleared out old order history. I can now go right through checkout and then select credit card (server) option [should this say direct?] but when I hit complete button I get:

The page isn't redirecting properly

Firefox has detected that the server is redirecting the request for this address in a way that will never complete
