I've waited a couple hours to see if you got any good answers.
I really can't help you, but this has worked for me a couple times.
The first time was legitimate; the next time, not so much.
I'm an "eBay" customer.
One day, I was having trouble bidding.
It was all the crap, cookies, or whatever on my computer.
I didn't know that, so I called eBay.
They have a call center in the Philippines with hundreds of expert people that are there to help you.
If you tell them you're trying to spend money on eBay and can't, they'll make sure you get your computer fixed up.
Their English is excellent, and they walk you through every step.
And, of course, it's free.
It took about 1/2 an hour to clean my computer up, but they were great.
Tell them what your problem is, then tell them you want to set up an eBay account (they do not do this), but you can't because of the trouble you're having with your computer.
I found this number for U.S. customers;
US eBay phone number toll-free: 1-800-322-9266 or 1-888-749-3229; 24-hour/7-day
Good luck.
