I have sold well over 100 items in less than 12 months and am also a Powerseller. I have the free relist box. Clearing cookies won't work alone, but try clearing your CACHE. That is what eBay CS told me to try, even though they said I may not qualify any more due to selling more than 100 items, when I lost the box a few months back. I cleared my cache, restarted my browser and the box reappeared. I have sold a LOT more since then and still have no problems ticking the box each time I want to list or relist an item.
