Unmaintained [8WR] XenCarta (Wiki) PRO 1.4.8a

I admit, I bought the wrong version. I wanted the version for XF2, but Isearched for XenCarta and stupidly clicked the first link. Once I realized my mistake, I asked the developer if he would transfer my license to the XF2 version – they're the same price, and I can't use the XF1 version anyway, so I didn't think it was a big deal. Nope. He flat out refused, so I had PayPal reverse the charge instead. Now I won't even bother with the XF2 version. Maybe this add-on is good – I can't say, but the customer service is pretty bad.
