(adsbygoogle = window.adsbygoogle || []).push({}); Hello!! sorry if i post this wrong section!!

i need help with my itunes!! it wont open!! i even tried plugged in both my ipad and iphone to my computer, still wont open!! i tried EVERYTHING!!!
When that day i realize that my itunes couldnt open when i double click on it (icon on the desk) then i tried it on 'Start Menu' still didnt open! so, restart/reboot my computer!!
and waiting my computer to load! then i try to open, Nothing!!!! i tried repairing, re-downloading it, unstalling it completely! then re-installing it, updating it and i even delete 'bonjour' when
they told to delete that!! so did, still wont open!! i tired Press "Ctrl+Alt+Delete" In the task manager go to processes, find itunes.exe, end that process, and they say 'it should work'
well, i couldnt find it, i only found iTunesHelper.exe, i didnt find iTunes.exe then i did some reseacrh on google and youtube!! all those things i did
(re-downloading it, repairing, deleting 'BONJOUR' etc.) those were the answers was givin out!! and seems a lot of people had same problem!! when that happened? well, that was last year november 2012 but i cant remember the date,
december thats where i tired everything, and january! so, i uninstalling it completely again, january to april, then i download it from that website! apple.com and NOTHING HAPPENED!!! :'(

when i had my computer!! i download it on apple.com official, i didnt download it from torrents, or any kind of iso apple websites they support!
ill tell you what i had inside of my itunes! i had over 3,000 songs type file was (mp3, m4a) and movies and music videos (mp4) and few apps!! and i think none of these music and movies can fuck up my itunes, right?
so, i think i fucked up my itunes because of Jailbreak and shit like that!! or maybe that i upgrade my iphone to iso 6 when isnt even release iso 6 yet!! then i downgrade it before they
release iso 6, so i can get the real official software!! so, thats what i think! or maybe there's some kinda 'Blocked Programs' program that can block my itunes, something like that! maybe im blocked by apple!! or im fucked by steve jobs!!
oh yeah, im using computer, not laptop, Windows 7....... So yeah!! sorry about my english!! i hope you guys understand!! please help me if you know how to fix it

If you bought music through iTunes it is still saved. Other music is stored locally on your computer and is imported into iTunes so no loss of data.

I have a jailbroken iTouch that I personally modify. It doesn't do anything to iTunes. You might have some damaged data lingering around that is causing conflict. Clear out your temp data and look for any other areas that iTunes would exist on your computer then try the new install.
