Blue tooth connectivity - failed

[reefs]

Hi, I'd be grateful for some help re a problem.  I am a user of spotify, currently still have it playing on my mac (no problem).  However, I have been using it via bluetooth (logitech audio adapter) through a hifi into speakers without any problems until I downloaded spotify on a laptop (windows) the other day.  Since then I cannot get spotify via bluetooth on my samsung (adroid) phone.  I also cannot get it via the laptop and have downloaded it to a axus tablet which also won't play. So all 3 bluetooth versions will not play.  The music comes out via the laptop, the mac, or the mobile, but stops immediately I link to bluetooth.  I have tried switching all off/on, reinstalling spotify on all the mobile devices, brought a new logitech bluetooth audio adapter, but all to no avail.  I also removed the programe from the laptop (as that seemed to have caused the problem) but has made no difference.  If anyone has ideas would be grateful.  I use spotfiy away from my mac, so makes it sadly not so useful to have any more....
