iTunes stuck processing file

Has anyone else had this issue recently? I am using the latest iTunes x64 on Windows 7 x64. When app updates download from the iTunes store, it freezes when it gets to where it says "processing file" and never completes. I tried using Ccleaner to clean empty junk off my compluter, ran a full disk defrag, and tried running iTunes as anmid, with the antivirus turned off, and the firewall turned off, but alas, it still keeps doing the same thing. I tried chancing allowing multiple downloads at once or only 1 at a time. I tried pausing and unpausing. I tried clearing the store cache. I keep having to cntrl+alt+delete and kill iTunes. No hardware or software has been installed lately to chance anything on my PC. Yet, it keeps doing the same thing. I plan on trying to reinstall iTunes and see if that helps. Anyone else noticing the same issue? Any solutions known that work?
