I have a Magento Community Edition website being built and want to trade on eBay using M2E pro. I need the M2E Pro extension configured to work properly. The extension has been installed using my LIVE site Id and I'm able to list to ebay but the syncing of inventory is not happening. I believe this is due to the cron job not being set up properly. I would also like a sand-box account set up. I followed a wizard set-up to do all this but I didn't really know what I was doing. Perhaps an unistall and fresh install is order?
