New version of Itunes is having problems with crossfading songs, it doesn´t work. How do I fix that?

Question

I installed the new version of Itunes (10.5.2.11) and I have a party playlist in wich I need the songs to crossfade for the music to continue playing non-stop.  The problem is that even when the crossfade option is activated, it doesn´t crossfade songs.  And when it does, the last song played, keeds playing in backgroung from star, so you hear 2 songs at the same time.
Also, I uninstalled the current version an installed an older version, but it won´t let me open the program, becouse "the iTunes Library was created in a newer vewrsion"
HELP PLEASE!!!!

It seems that this is a MAJOR issue with MANY end users experiencing the exact same problem - iTunes 10.5.2.11 Crossfade is completely buggy.  Apple, get it together, seriously...your QA department should all be fired for this.
Diego, there are numerous threads replicating your problem.
So far, there are a few work arounds:

One thing to keep in mind, at least what has worked for me: After you make a change to the crossfade timing, you must close out of iTunes and re-open before the new settings take place.
Crossfade timing = 12 seconds actually equates to about 50 seconds.
Click the slider, then use your arrow key to tick over about 20 times - this should crossfade your songs approximately 6 seconds before ending.
Apply, then close out and re-open iTunes...
Peruse through the link above, there are different approaches.  Maybe one will work for you.
