Suggestion for place to sell Embroidery software

Does anyone have a suggestion for a place to sell some embroidery software? I have an ad in the classified here, but as of right now still no one has even inquired about it. I really really need to recoup some money on the purchase and need some help. I have listed it on Craigslist, 5 Miles, and Offerup already. I know this is a limited market to sell this and maybe i'm being to honest. It has two activation's to use when bought new, but I've burned one only to find out it won't work for my needs. The stupid company refuses to help me or release the 1st activation so I can sell it completely. I can even prove I bought a second software to show them I'm not trying to do anything fishy.

Thought or help would be greatly appreciated.
