It's just as it says...  "Unable to load DLL 'asmcheck.dll'"  Make sure asmcheck.dll is in D:\Program Files\Terrarium 1.2\Client.  If it isn't, re-install.  If it is, you'll need to figure out why it can't be loaded.

Hi I've got a the same problem has the dll is where it should be are there any more ideas as to why this file wouldnt be loaded?

Hi I'm not sure if this is still a problem for anyone else but I've found if you just install the latest versions of the .net framework it'll work fine
