I just get directed to http://volkswagen.msk.ru/error.php
What happens when you go to the home page
http://volkswagen.msk.ru/ ?
and when i right click and save as, it says the file is damaged and doesn't open. This is true for all engine pdfs.
I'm downloading them again now, and they are all comming down my sloooooowwww dial-up pipe as I type, and they all open OK!
Try downloading (right click > save target as) any of the English docs from the above Rusky homepage!
What browser are you using? My similar effort on the Mk3 board also gave the same probs - until someone owned up to using FirePox. They switched to IE, and all was perfik! Pop over to the Mk3 thread, and look at my other suggestions!
