hi, the exact error message got cut off unfortunately. could you paste it again including the error code? thanks...
I'll paste it again when I'm on a PC again. It said SSL had received a response that exceeded maximum length. I have a screen shot of it I can paste tomorrow.
I'm using Avast AV, and just the WIndows FW. I did not delete the FF folder. Thought I'd done a full uninstall but the reinstall recognized that the folder was there.
