Did you report it?  At the bottom of each store page there are a collection of links.  You want Get Support under Let Us Help You.  That's at the bottom right side of the page.

Stripe appears to be the system Hivewire uses for the checkout / credit card validation process.  

Since you just got the error Thursday, and I had it a few weeks ago, but did not get it when I placed my order Wednesday, it may be a random problem, which will make it difficult to find.

Though I really hate using Paypay, that's how I got around the error a few weeks ago.

Quote - . . . I'm trying to buy all the Dawn morphs from Hivewire right now, including the mini sets, but the system keeps saying "invalid stripe" something or other.  I can't find a link to post on the forum.  It's as if they want to make damn sure I can't buy anything.  lol.  Come on, guys.  This is silly.  How can I buy your product??
