i have the same problem. After loading the latest bin fix display rolls puff a couple of times and then holds on F for 8 sec. continues to do this over and over until switched off with the rear switch. Tried running convert to puff 1.0.1 step 2 again...as soon as i load the new fix i have the rolling puff issue as if it hasn't accecpted the new file. re-loading the file does not help...any thoughts??
