Are you installing the full version of Webman or the lite version? I've heard people had same issues with the full version but lite version worked fine, if you have the time install the lite version to see if that works.
If webman lite works fine, install multiman and see if that works with webman lite. If you dont encounter any issues let me know!
Wow, just installed 1.47.34 in lite mode and it works flawlessly. Could load my backups and no freeze at all.
Thanks a lot man, you're a savior!
