You can't load MWLL from the Crysis Wars mod loader menu. That's why you're not getting any servers.
Try using the launcher again and giving it some time, to make sure if it's actually freezing or not. Also, you may need to disable any antivirus you have running, as some has been known to cause issues with MWLL.
As for the downloaded files, they are located in My Documents/My Games/Crysis Wars/MWLL/Updates
Please feel free to use the forum search if you have any further issues, so not to push this thread off-topic. Or perhaps make a new thread in the appropriate section.
