Error during installation

In the past 2 days i've tried to re-install my WoW due to some errors.
on my first try i installed wow vanilla and burning crusade from cd's and it worked pretty good but when i tried to install WOTLK i've got an error and i thought it was because my dvd was scrached and i tried to download it but still the same error pops and looks something like this:

Q u o t e:
An error was detected while verifying the contents of the file "D:\World of Warcraft\Data\common-2.MPQ". There may be a problem with your system, or with the drive at D:\. You can attempt to install again. If this problem persists, please contact Blizzard Technical Support.

After that i've uninstalled wow completely and tried to fully download it from http://www.wow-europe.com/en/downloads/client/ but around 8-9% of installing ( the download still continues) i get a message like this:

Q u o t e:
Please insert the CD labeled "Wrath of the Lich King Disc {Disc},"

If i press Yes, nothing happens ( and yes the dvd is in the dvd rom) and if i press No an error pops up:

Q u o t e:
The installer was unable to read the file "E:\Games\World of Warcraft Installer\Installer Tome 2.mpq". This error may be caused by problems with the media or drive at E:\ --for example, a scratched or dirty CD-ROM/DVD-ROM, hard drive corruption, or a networking problem while downloading the installer. (The data being read was "MPQs-1\Classic common\unconditional\Data#common-2.MPQ\Creature\Ogre\Ogre0069-02.anim", and the error code was 8.) If this problem persists, please contact Blizzard Technical Support. (Converter::Load)

I said.. ok there might be some problems at blizzard websites, but now when i'm trying to install wow using my dvds i can't, i get an error at around 50-85% durring the instalation wich is something like the last one.


and now my part. I've tried almost everything:

Windows re-install
Full Hdd virus scan and error scan
I've copied the content from Dvds on Hdd and run install from there
Run the install in Safe mode

Thanks for your time and i hope there is a solution

EDIT: Tried again to install the game, it worked perfectly fine til WOTLK when at 67% i got this error:

Q u o t e:
The installer was unable to read the file "K:\Installer Tome 4.mpq". This error may be caused by problems with the media or drive at K:\--for example, a scratched or dirty CD-ROM/DVD-ROM, hard drive corruption, or a networking problem while downloading the installer. (The data being read was "MPQs-2\unconditional\Data#lichking.MPQ\World\maps\Northrend\Northrend_38_24.adt", and the error code was 0.)
