Hello all,
i´ve problem. I bought "Machinarium - Collectors Edition" on amazon.co.uk. So far so good. As I revieved the package, there was no "Windows-DVD" inside only the "MAC-DVD" and the Soundtrack. 
So what I did ? I wrote to Mamba Games (think the customer service guy was "Jason Codd") and asked them to send me the correct version. 
Till today i recieved nothing 

.
Help pls this is sad.
best regards
