Hi,
The links of the standalone are not working: http://www.wsmostudio.org/download/WSMO-Studio-linux_x86_gtk2.zip or http://www.ontotext.com/wsmostudio/WSMO-Studio-linux_x86_gtk2.zip.
I having problems installing the plugins, so I think it can be better to try the 'frozen' version.
Thanks in advance,
Carlos A.
This is the place where the latest version of the studio is archived:
