Ok, been working on the iOS part of my Shared project last few weeks, came back to the Android part of it, clicked build all, went fine, then play.
Xamarin Studio told me there was an update for the player (XAP-Beta-15.29-v0.4.4.dmg) which I downloaded and ran.
Now I cannot seem to run my Droid project on simulator because Xamarin tells me there is already a player running. It does this even if I close down the player beforehand...
IS this a common problem and how is it fixed please?
