Thread:Project:Support desk/Error with running Pywikibot: "Token not found"

I've been trying since yesterday to run the first edits of my new bot. I've already set user config file (the system is windows btw), and I can login and insert commands pretty normally, however, every time I try to run a script on wiki articles I get a lot of strange error messages. They say: "WARNING: Token not found on wikipedia:ar. You will not be able to edit any page" and "Received incomplete XML data. Sleeping for 15 seconds...". There's some guy here who has got exactly the same problem, I've tried to perform the suggested solution (updating Pywikipedia), but nothing has changed. I've just finished an hour long discussion with a guy from the IRC, without much outcome. Suggestions would be very appreciated!
