Go to Windows/System32 and delete wpa.dbl and wpabaln.exe. (wpabaln.exe automatically reinstalles itself but it doesn’t matter, don’t panic )
Download Windows Product Key Update Tool from Microsoft.(google it). Run the tool and change the product key.
Problem solved.
Create a txt document (Ex: pcs.txt) and write the computer names in it like this:
PC1
PC2
…
Copy the script below, paste it in a txt document and save it with the .bat extension.
The script copies the ie8.exe kit from this location \\mycomputer\c$\IE to the stations listed in the pcs.txt document. After the internet explorer kit is copied, psexec.exe tool installs it. If you don’t have psexec download it from here:
You must open the .bat with a domain admin user (administrator rights on the remote computers). To do that press Shift Key and right click on the .bat, Run as different user. Type the user and password and the script does the rest.

This happens because Data Execution Prevention is on.
There are two symptoms of this error. One is the Data Execution Prevention window with the message specified in the title (To help protect your computer, Windows has closed this program) and the other is res://ieframe.dll/acr_error.htm error.
Solution:
Go to Start->Run , type %systemroot%:\boot.ini (in most cases systemroot is the letter C) and hit Enter.
A window will open.
Search for noexecute=optin and change it to noexecute=alwaysoff .
Save (Ctrl + S) and restart the computer.
Problem Solved.
This only works in Windows XP.
Click “Start” and then “Run.”
Type in “regedit” and press “Enter.”
Search for the following:
HKEY_CURRENT_USER\Software\Microsoft\ Internet Explorer\Desktop\SafeMode\Components
Click the value written as “DeskHtmlVersion.”
Select or click on the “decimal” button.
Change the value to read “0″ instead of “272.”
Refresh Desktop.
To verify the Internet Explorer Version on a remote computer you can use psinfo.exe.
PsInfo is a command-line tool that gathers key information about the local or remote Windows system.
PsInfo is part of PsTools and you can download it from here.
Open a cmd window with administrator credentials. The credentials must be for a member of the local Administrators group on the remote computer.
To do that , go to Start ->; Run and type : runas /user:domain\user cmd and hit Enter . You will be asked to enter the password.
After the window opens , use the code below.
For a list of computers:
psinfo @pcs.txt |findstr /B "IE version:" >> "C:\IEversion.txt"
For a single computer:
psinfo \\computername |findstr /B "IE version:"
This is very useful for stations without an antivirus client installed.

I have restricted access to YouTube. http://www.hidemyass.com helps me with this problem. The streaming is filtered via their servers and it works just fine. The video quality is lower , but is better than nothing.
You can use hidemyass for other websites as well. Give it a try 
It doesn’t work on sites where you must login, like Facebook, Gmail or others.
If hidemyass is also banned, then you can try an online video downloader.
