I just downloaded version 6, and I'd like to know if it's better to uninstall version 5 before installing 6. And, van I use both versions at the same time?
Also, I've been using version 5 and have all the settings and scores. Is it possible to migrate that from 5?
It should be no problem running both versions in parallel. I am not sure however that results can be migrated from v5 to v6 since the lessons are all new.
