Tips and tricks needed to survive the Math U See online

I am about to lose my dang mind. First day of homeschool in our 4th year. I decided to try Math U See math for my son. I spent $300 on it between the course, manipulatives, and fraction overlays. So its not cheap and i figured we would kinda...ya know...get what we paid for.

How in the hell is their website this baaaaad?! Forgive me because i have been fighting this for 2 hours at this point and their stuff loads slower than 56k dial-up internet in 1995.

Please, please, please someone help me learn to navigate this hot mess garbage, so we can just load in and click on videos.
