2.5 Woes

So im always loathed to update mixvibes as i always run into problems usually after just getting everything set up nice.
I kept putting off updating to 2.5 but the key detect drew me in.
And ive had a night of frustration and was hoping someone on here could help.
My big problem is the way sync now works, my set up is simply 2 turntables (DVS) with a basic controller.
I had mapped to a button the "sync player a with player b" feature and vice versa to another button. Did what it said, i could sync one player with the other with one button press.
Now that doesn't seem to be in mapping, i have "sync with master" or "match bpm with master" etc
To start with i couldnt even work out which deck was the master, it seems the only way i can view master is by putting it in 4 player view. Which i don't need and takes up most of the screen.
I also now have to map spare controller buttons (that i dont have) to assign a deck to be master, to then sync the other deck to it.
After working out which deck is actually the master i gave it a whirl but it just doesnt work for me, if i hit sync it does sync the beat but the bpm is always off so it quickly looses beat lock.
If i keep hitting sync the bpm jumps around but its never close enough to hold lock
Before with just the sync button it would match the bpm very accuratly and lock the beats. now it can't seem to match the bpm at all even if i use the mapped (sync bpm to master) only it doesn;t get it right.
And a last niggle, i browse songs throught the iTunes playlist and it doesn't seem to display the keys at all. Only untill i load a song can i see it above the player. I can see it displays keys if you browse via collections or something. But i never have used anything but iTunes.
Kinda pointless if i have to load a song just to view what key it is.
I always seem to run into problems with mixvibes it gets so frustrating, any help would be appreciated.
Cheers
