I have been working on Solo Play in order to sharpen and improve my driving skills. I have gotten to B05 and gotten a Bronze medal time. However, now, when I open this track to try to do faster (and open the next 5 tracks) the game does not provide me with the option to play. Nothing shows up in the opponents window. What am I doing wrong?

Any assistance would be welcome.

This is a known bug.

Chances are you've downloaded the track at some point and now have it separate from the campaign as a track file in one of your folders.

Most likely:
Documents\ManiaPlanet\Maps\Downloaded\TrackMania\Race\[Environment]\Nadeo\

Delete any files there and restart ManiaPlanet.

You should have the option to play the track now.

This was the answer. I removed that track from the downloads folder and was able to access it online again. Thank you.
