hi aubidamax

plz re-upload the doc the link is dead

thanks

why you send docs without sending the password...this is not good..we download the document then we cant extract becuse the password...

Check Default password section...!!!!!!!!!!!!

Check Default password section..and you can find it

[Stantheman]

Aubidamax, it would be helpful if you referenced where your default password is posted , instead of people having to search through 43 pages of posted passwords , it is here http://www.finetopix.com/showthread....l=1#post148989
