spotify under wine opensuse 12.3

I realise I'm in danger of being told to go to Spotify forums, but I'll start here anyway.....

I have opensuse 12.3 and have just installed wine 1.5.23, and then run the windows spotify installer which appeared to install OK. Spotify started fine but then displayed a message which said

We're sorry you appear to be on an unsupported platform

and then exited leaving no trace.

This may be an existing and old problem so apologies if it's already been dealt with, but any clues would be useful.

If the moderator wants to send me off to spotify forums then any help with previous posts in those forums on this topic would be welcome!!

Thanks
