WockySlush The license was suspended because you where breaking the ToS. We also had to take down any WHMCS licenses because we found out that the place we got the licenses from actually where not autorized to sell them. As soon as we where made aware of that, we had to take it down from the store.
We used our own WHMCS license system for our WHMCS install, but after this we had to go to the official site and get a key.
If we didn't revoke your key, it still would have ended up with the same result, you not being verified.
