Backtrace of Wine-Mono-Installation

While installing 'Leagues of Legends' via PlayONLinux-wine-1.7,
I get the final stopper. (Please see attached backtrace)

The first message which I got stated :
- Wine could not find the Mono-paket.
  It is necessary for .NET-programs in order for them to work correctly.
  Wine can download and install the paket for you.
> I then pressed "install"

Dowmload started and was interupted 5 seconds later with a message-window :

- The program control.exe showed serious problems and had to be discontinued
> the backtrace details can be seen in the attachment.

Please help - I am not quite a LINUX-guru

I am using: Ubuntu 12.04 ( 32-bit )
