The code we give for insertion is not scrunched. If your listing program "scrunches" it then you should contact them for support. I can't possibly see what we could do to stop the scrunching being done by another program. The old code and new code are entirely different and there is absolutely zero chance we can make our new code look or work like the last code. eBay completely changed how their site works and we had to adapt our code accordingly.
AuctionSoftwarReview is hardly a reflection of the satisfatction of our userbase. Happy customers have no need for such a site and aren't out looking for sites to leave great reviews on. Sure if we sent an email to our users to leave a review maybe 5% would be bad, but the other 95% would be great. The question then is whether there is something I could do better to make those other 5% happy, and whether there is any other systemic type of problem going on. As far as I can tell neither of those are representative of your support issue.
There must be 50+ listers for eBay. There is no way to test them all, that would cost a fortune.
You sound like a loyal user who just wants to get it working, I'm not sure what all we can do though. This may be a case where a refund is the best solution.
