Downloading Issue

I'm having problems with the downloading function. I like the ability to download so I can take the lessons with me to practice where I don't have Wi-Fi access. I try to download, and almost every time, the download fails. I have to retry sometimes 2 or 3 times, and finally get the lesson. But each retry counts against my 15 a day limit. So for example, today I was able to get the first 5 videos of the Country Style lessons, and reached my maximum of 15.

I contacted customer service, and through them determined maybe it was a browser issue (I use IE). I switched to Chrome, which was even worse. So is there a way to find out why these downloads are failing? Is it a security issue on my side and I need to adjust a setting?

I would guess your internet connection is intermittent?

Try a broadband quality test (not a speed test).

I just found this one:

http://freeola.com/line-test/

What does it say when you try it?

It gave me this message:

Unfortunately the line test has failed to complete, due to 100% packet loss. This means that we were unable to connect to your computer via a ping request. The most likely cause of this problems is firewall software that is set to block ping requests. This firewall software may be installed on your computer, or built into your router (if you use a router to connect to the internet).

And yes, I do use a router for my laptop which is the computer I've been trying this on. So it's connected wirelessly.

I'm using Kaspersky, and windows says it's controlling my firewall, so perhaps it's an issue with that?
