Greetings All, I purchased the add-on thru the link here and was able to get the game from D2D but the activation took over four days , Jason at ubisupport pointed me back to Direct 2Drive as the culprit , but without contacting them directly the activation finally worked!I just tried it again hoping with fingers crossed the next day and it was worth the wait , I missed the uboats after moving to sh4.Its a great addon!
