Very Peculiar, URGENT Problem

Hello all -

I'm a student studying medicine and am preparing for my medical boards in two months. The training program I use is called Doctors in Training (doctorsintraining.com), a really great resource which teaches through posting videos. However, a few weeks ago all of the sudden, I was unable to stream their videos for subscribers. I can play flash media on ANY other website except those that I REALLY need which are limited to their subscribers. The message I keep getting is, "Unable to display video: you either have JavaScript turned off or an old version of Adobe's Flash Player. Get the latest Flash player." I have been working with their tech crew for 6+ hours in sum, and it sounds like they're about stumped. Hence, I'm reaching out to y'all!! Here's a summary of details about this situation.

- Lenovo T410 w/ core i5 processor

- Windows 7

- Up-to-date on all system drivers and have all windows update

- I have NOT installed any new programs that I can remember. System restore mysteriously doesn't want to work either.

- Problem occurs on my main laptop, my tablet (a sony tablet S), and my girlfriend's Toshiba

- Problem occurs on my network, or on other networks if I'm using my own hardware

- If I sign in from another computer on another network (eg public library computers, I CAN access the videos.

- I run webroot security software. I have tried to disable it which does not help. A complete scan shows no viruses. I did a secondary virus scan with another provider which didn't find anything either.

- I have switched routers and the problem persists.

- I have uninstalled, reinstalled Flash using Adobe's installation software.

- The problem persists on Firefox, IE, and Chrome

- I have done everything suggested by Adobe Support pages prior to posting here

- I have uninstalled and reinstalled Java

- Javascript is turned on in all browsers

I think this pretty much captures the peculiar aspects of this issue. The IT guys over at DIT did a remote access of my computer to verify the code my computer is receiving from the site. Evidently, there is a problem that somehow the videos aren't queing up due to some faulty code, but I am the ONLY person of their 10k subscribers that has this issue. They're not sure how to fix the problem.

PLEASE HELP!!!!
