I installed Genimotion (v2.2.2), but I seem to have problems with it, as I couldn't play the devices I downloaded for it (tried several devices).

I tried reinstalling VirtualBox (v4.3.10) but it didn't help either...

Now I want to try reinstalling the Genimotion itself, but I cant find an uninstallation shell or any way to uninstall it (I also tried running the command: 

> 
> sudo apt-get --purge remove genymotion
> 
> 
> 

in the installation folder, but it didn't detect and removed the files).

I saw many people who suggested reinstalling it but never they didn't mention how, so I hope it's not a really stupid question...

Thank you
