I have some files here which have been downloaded as a series of parts which are then supposed to be put back together after running a bat file. This process has worked fine up until today and now when I run the bat file I get an error stating Windows cannot access the specified device, path or file. You may not have the appropriate permissions to access the item. When I try to edit the bat file I get "Access Denied" my machine is standalone, I have full admin rights, and I can't get it to work running the bat file as administrator either. Its as if Windows has suddenly decided that bat files are banned. I've also disabled my AVG Internet Security incase that was causing the issue. Any thoughts guys?
