10 years agoThe error you are receiving is more directly related to the USB blaster driver than the Quartus II Project. I'm wondering if the USB Blaster driver was updated when you install 14.1 and now there is something incompatible with 13.0 when it tries to talk to it?
I'm assuming you are running the Windows version of Quartus? Pete
