I've just compared the 4.1 zip file, which I was originally sent in error, to the 4.2 zip file which you sent to me last week. They are very different. Doesn't look like a minor upgrade. I wonder if either WebsiteCM or BCSEngineering have sent me the wrong file(s).
Secondly, when unzipping the 4.2 zip file, I received an error:

On checking the zip file, I found two func.php files in the modules/BCSE_Reward_Points directory One is 21,202 bytes, the other is 8,993 bytes.
I think there's something wrong with your distribution.
I've also updated the support ticket.
Thanks, Steve.
