@Irrelevant: Since you did not mention that you have the well known “no command” message before, you cannot blame recommending you non-helpful links (as they were adressed to @evidemment anyway).
You searched already for “no command” in the forum?
Then I guess you found already this links:
Trouble Shooting Article
Forum topic 1
Forum topic 2
Report back if you succeeded or not…
Cheers, Robert.
