Ebay .com and .uk wont let me sign in says the information is invalid, ebay told me to clear my history, passwords, cookies and stuff, didn't help. my isp said there not blocking anything at there end. changing password allows me to log in but when i log out i cant log in again. Cant find any spy, malware or virus. Win xp home sp2 Mozilla Firefox - 18.104.22.168 IE7 any one had this problem?
