Thanks for that, I downgraded and then re-upgraded to see if it would make a difference to my SD Card problems, but in both firmwares it says SD Card removed, but, during the update process, if I enable LCD updating, it writes the LCD firmware to the SD card, so the it is obviously able to communicate with the card and make changes to it through the USB connection even though I can no longer access it from the menu or write to it from any software while installed in the printer.

It seems like Z-axis goes to the opposite direction.
You can use motor tool to change it:
