Thanks for the note. I found the transaction record in vBulletin but your title wasn't updated, which indicated something was broken.
After some research I figured out it was a result of the <a href="http://en.wikipedia.org/wiki/Year_2038_problem"> Year 2038 Problem</a>. Since it is now 2008 and I had subscriptions set to 30 years, it was giving an error when it tried to process the subscriptions. I manually fixed yours and changed the subscriptions to 29 years. I'll go back and check any other subscriptions that may have been affected.
Thanks for your support of the site!
