You should not have been charged, contact RO for a refund.
The online training changed, we have been talking about this since November, in fact I made several posts in the Online Training Section about the changes.
I have also posted at least 3 updates on the subject to include a Blog Post.
Contact Rifles Only get a refund on Feb 6, if you want back, the new system is up, however all the old lessons are gone and will not be returning.
