I recently had to reinstall my pc after the hardrive began to fail. I managed to backup all my data, including my Zwift activities since 2016. After reinstalling everything I copied all my old activities in to the Zwift Activity folder, however at the end of my rides the Critical Power chart only displays data from my rides since reinstalling Zwift and none of the old rides.
How can I fix this?
Did you copy over the \documents\zwift\cp folder? That is where that data is stored.
Ah no, unfortunately not, damn it.
