Yes i have spent a few hours trying as many things i can but it will not open for anything i try and do.
Please try using The Unarchiver (https://theunarchiver.com/) to open the file. It should be able to open the .rar!
I have tried but i did it again just to make sure but it did not work.
If you send us an email (firstname.lastname@example.org), we can try sending you the files in another format.
