Trying to copy txt file in Notepad. "Notepad: Access is denied"



If I had known how much hassle Win 7 was I would have stuck with XP! Well I suppose its a learning curve....
Latest major hassle, I have a text file on my E:\drive, this is a copy of my XP C:\ drive before I installed Win 7 on it.
I have now been able to get to it after changing the security settings, and then tried to drag and drop my Blacklist.txt to a newly installed version of the program (Mailwasher Pro) on my C:\ drive. I was not allowed to do this as "Notepad: Access is denied", I could not open it either to copy as again "Access is denied". What ever I try access is denied. This applies to Wordpad as well.
I am setup, as far as I can tell as administrator, I have printed and read the tutorial - Permissions - Alloy or Deny Users and Groups. but this did not seem to help, when I open the security tab it shows:
System
and a long, long set of numbers, there is no administrator or user information as I have seen in other Security tabs.
It was dead easy in XP just drag and drop or open in Notepad and copy paste across!
Is there a way to get around this problem?
