Unfortunately due to an error in the SDN protocol, I was forced to make it so that every one must now use the newest version of OSBot. This version however has had a lot of bugfixes and should run way smoother than any older releases. An error on my part as well was that I released 1.6.8 without testing if the bugfix actually worked.
If any scripts have been broken, now is the time for them to be updated.
Sorry for your inconvenience, the newest download is at http://osbot.org
Sincerely,
Laz and the OSBot Team.
EDIT:
The good news is, OS Agility, a soon to be premium script was just released and should work on this release. It's in the SDN and is free while it is in BETA!
