VB 4, Problem With Subscription System

[Authentex]

I have 15 different subscriptions setup for different products on my site. If a user has a sub to one product and tries to buy another product it seems to cancel out the first product.Then I have to manually go in and add the other product back so they can see that products VIP forum again.

How can I fix this? Adding each sub is not an option as we have 200 or more daily!
