Any issues with credit cards due to Chaosium purchases or something like that?

Phone them.
The vast majority of answers can be got quickly from their intelligent call centre staff. These you should be able to speak to as you are a seller.
If you're unlucky enough to be routed to their phone monkeys in the middle east, ask for staff that speak english or italian, and explain that you don't understand what they are saying and can you speak to a manager. You might get lucky and find one with a brain and the ability to understand words.

Cross your fingers and hope for Ireland or the US.
