Virtrium has released their new billing site!

Note:  If you have an existing, active subscription through PBT (the old system), wait a bit.  Virtrium is in the process of transitioning those to the new billing.  There is no need to go and cancel it at this time.

Note 2: All accounts are still comped for a few more days.

Note 3: For more information, see
