I'm on my 3rd week of unit 2 and it still says my code RP02OWP is an invalid code.  I am using a Samsung tablet. There was no problem accessing unit 1. I have tried rebooting the tablet to no avail. I would appreciate some help. I can be contacted at davidedwards50@Hotmail.com or 360-661-1373.

I'm on a Samsung tablet and it keeps saying I have an invalid code. I'm typing it correctly. I would sure like to use the resources that come with this curriculum before the unit is over. I can only see unit 1 resources. I need unit 2.
