I did. Installed as always... 1.5.9 worked without problems.
Edit: Well, it works now and here's what I did.
1) Install 1.5.9
2) Run it, run the connection wizard so that MPE finds your phone.
3) Exit 1.5.9
4) Install 1.6.0
5) Run MPE
Now it works and doesn't generate any errors.
Edit 2: Well, this should be in another thread but I suppose you'll have a look at this too so...

^ There's a german line in that window and I'm using english language file. Even though I can understand it, I think it should be fixed
