[yt-users] Rollback to yt version 2.x problem

[trobolo dinni]

Hi Matt,

in the end I solved the problem by fully reinstalling yt using the script
for the 2.x legacy version. I missed that from the main download page one
can get the script pointing to the older version.

Thanks for the suggestions anyway!
