Class 90/Mk3 DVT Update
Many apologies about the problems experienced when purchasing the Class 90/Mk3 DVT Pack tonight due to overwhelming demand. Unfortunately we have been unable to return the website to a satisfactory state of stability so refunds have been sent out for those who managed to make an order. As a result of this instability though, we have had to take the Class 90/Mk3 DVT Pack off sale until we are satisfied our server has been upgraded sufficiently to handle the traffic.
Apologies again and we will be working all hours to get this pack to you.
