I've been having trouble where whenever I charge up my Aspire, the readout show 0 ohms and I have to remove the battery and put it back in so the thing will work. The vape shop told me to download the latest firmware. I plug the device into my PC, and download V7. It wants a rar file opener (never heard of rar files before). I've tried several from the windows store but I get errors, and also see no way to get the firmware to my Aspire. It's plugged into my WIndows 10 USB, When i look in my drives, there is nothing showing the Aspire. I've tried multiple USB ports.
Unrelated, my readout keeps asking me "new coil?" sometimes even after I recently put in a new one. Is this a glitch, or?
