Ebay question: mass editing of items

I have been unable to use the mass editing function ebay for over a week now. I go into "My Ebay" and click the edit button, but the page doesn't load. Before it would show some items and allow me to edit them, no longer.
Running an Ebay store sure takes a lot more time than a person would think!

TurboLister is usually the easiest/fastest/best.
Try doing only 6 to 10 items at a time, to start.
The thing often dies if you check too many items
at a time.
Thursday is the night they feed the hamster that powers the servers.
You could be caught in the chow-time slowdown.
