ITunes 11.0.4.4 crashes when I play certain songs and the problem is spreading.

Question

Ever since I downloaded iTunes 11.0.4.4 (for windows 7), the program has been crashing whenever I play certain songs and at this point the problem is spreading, more and more songs that weren't problems before. I have been through just about every troubleshooting step I could find more than once, reinstalling, safe mode, conflicting programs... if a solution out there was even vaguely related to my problem, I've probably tried it. The only modification that I've made to the program is enabling 1/2 star ratings, and I don't think that's the problem because the earlier versions of itunes worked fine with it, and I've tried temporarily moving the itunes preferences xml to make it generate a new one, and it didn't fix anything.
My library has over 14,200 tracks so I can't possibly delete and then re-add all the problem tracks to iTunes, and even if I could, I've tried doing that with a small number of specific songs already, and while it worked at first some of them have started making iTunes crash again at this point.
I understand that the problem is most likely that my library is corrupted, but I'm very wary of the solutions to that problem that I have seen because I have had to use them before more than once, and each of those times I've lost thousands of songs (last time it was 5,000 tracks) in the process and a shockingly large percentage of the tracks came back disorganized and improperly labeled (some of them as 4 letter strings of capital letters that I can't seem to identify without using shazam) and without ratings ( I have "keep iTunes files organized" and "copy files to iTunes media folder when adding to library" in preferences checked.)
It takes a huge amount of time to redo the information for the amount of tracks I have even if you buy software to help automate it, and it would take me 5.7 days to redo all of the ratings I've done, and ratings are important to me. I've added a lot of new tracks since then and my library is still 2,000 tracks smaller than it was before i had problems last time. The solution scares me enough that I've put it with the crashing for two months now, but it's getting unmanageable. If anyone can give me a way to fix this that would leave my library intact, or at least minimize the damage, I would be extremely grateful.
Thanks.

I had this exact same problem.  I found a fix on another support post that worked perfectly for me.  Browse to C:\Program Files (x86)\Common Files\Apple\Apple Application Support and copy the filen named QTMovieWin.dll.  Then browse and past that file into C:\Program Files (x86)\iTunes.
Hope this helps you.  My iTunes store is working fine now.
God bless!!
