Keepers of the Glade

well, i dont know what i did wrong, or even if i did anything at all, but it seems like something is broken in my puter or my email itself.

i have 3 emails, 2 of which is still currently working and the 3rd is somewhat acting weird, lets save the semantics and go to the detail. when i log onto yahoo.com, i put in my regular email addy, which is paulimon14@yahoo.com yet somehow the page wouldnt pull up, so i tried to delete all the cookies i have and allowed all the cookies that way i open any passage, then i tried logging back on, and it still wouldnt work, it kept on pulling a blank page. so i got pissed and decided to play outside, blah blah blah, then when i got back in, i tried to log on paulimon00@yahoo.com my other email addy which is more personal for really close friends and family only, and now that since you all know that, dont spam it =p lol jk and then it pulled up the page perfectly, so i logged out and pulled my Yahoo Messenger, and then logged on my paulimon14 account, and it says i have 5 new emails, so i tried to check it, and it still kept on pulling blank page, so i tried my third account which is anitran101, and then it pulled the page up without any problem. I personally have no freaking clue what the hell is going on, maybe someone in here is computer literate and maybe can help. lol ive tried everything and still not working, so im really desperate so please help =(
