I just opened a free trial account and tried to manually upload 3 months worth of individual ride data files (24 total), as directed by the app. However, when I clicked the finish button, I got a ton of messages saying that free users can only upload once per week. Then I looked at my calendar and saw that only my most recent data file had been successfully uploaded. I have to say that this is a very poor user experience. I wasted a lot of time downloading the files from trainer road and then uploading them back to Xert.
