Q: Why can't i update my itunes?, Why can't i update my itunes?

I have had this iTunes for a while and I don't think it's updating because I don't have the iCloud on it and it's hasn't connected with the iTunes Store either. I constantly try to connect the iTunes Store but it never works, I always make double check that I do have Internet on my laptop but it never works! I don't want to Re-install my iTunes because i have more than 500 songs and i do not want to lose them all. Everytime i check for updates it says "The iTunes update server could not be contacted. Please check your internet connection, or try again later. when ever i plug in my iPod or iPhone, it syncs perfectly but i can't access the iTunes store from my laptop, i can't use the iCloud because it's just not there and I also can't get my purchased songs on my laptop.
