That's why whenever I'm asked about shopping carts (or if I need one for my own use) I also consider a few options: Magento (#1), OSCommerce, OpenCart and PrestaShop.
Not only is there ample support for each online, they are plenty of communities dedicated to it.
I'm sorry to hear about this happening to you, but thank you for posting this warning to share with others
I have ALS, mostly paralysed, and was in desperate search of a suitable shopping cart solution to continue the family business when I no longer could. The reason I mention this is to clarify I was looking for a solid, easy to use, feature rich shopping cart with good support. After all, when your income is dependent on the software working, you want to make sure there's quick resolution.
