Hi Paul,
First thing to check is that the file you have downloaded has the extension ".zip" if its anything else then rename it to ".zip".
Assuming it is a a zip file (which it should be) you need to change the program that opens it from adobe to winzip, winrar or compressed (zipped) folders. WinZip and winRAR are both free trial software but compressed (zipped) folders comes with windows.
To change the program that open zip files try this:
right click the zip file.
click Properties.
click the "change" button.
then select either of the programs above if you have them.
Assuming your on windows then you should definetly have the compressed one.
This will change the program that opens zip files to the one you choose.
once you are done try opening it up again.
Hope this helps
