If you want me to upload the version I have then I'm more than happy to.
I've double checked it both runs and calculates things correctly.
I've also got the following installed:
Collections Manager
Kindle Dev Certs (Had to readd that after updating to 5.3.4)
Python
screensaver hack
Just so you know what's running on the system.
I've tested it on all of the Paperwhite firmwares as they've been released and it's worked on all of them for me.
Any further info I can supply to help, then please let me know.
