Meridian use a third party open source framework called Mono to allow Control:Mac and Control:PC to be developed using common source code. I dont know much about Mono, but it looks from the stack dump that the error is occurring in the early stages of Mono initialising, possibly in areas where Meridian have very little control. My guess though would be that its far earlier than any networking code so networking issues like firewalls are probably red herrings.

I can't help any further other than to suggest that if you have another app that may use the Mono framework, try deleting it. I don't know how Mono is installed and whether it is linked directly to the app, but if the frameworks are shared between apps, there is the chance that there is a conflict between different versions of Mono. I realise that you probably don't know what other apps may use Mono, but if you have any other apps that have a Windows version that looks and feel similar to its Mac version, then it may have been developed using Mono. Likewise, if you have any system files that clearly relate to mono, try also deleting those.

If you like digging deeper, try the section on wapi for starters as it looks to be involved in the crash.
