[Wine] Bad .EXE file?

[Jetbird_D2]

Hello!

I faced a very strange issue with wine. So I am trying to launch my beloved app that works under wine 99% good, but after upgrading to Ubuntu 11.10 I get this problem (extraction from terminal): 

wine: Bad EXE format for H:\Desktop\Carrara  8.1

I get the same problem if I go to the 'hidden' wine folder and go to c drive and launch it from there. 

any advice on this? 
Thank you very much! 
Kind regards,
