I have a model 1525. I initially had it set to mode 1 for two weeks but changed it to mode 3 today to get data transfer to switch off of "waiting". After reading another entry in this forum, I unplugged the display and restarted the computer, and I now have "transfer now" after plugging the display in again but it says there is no data to transfer. I hope switching from mode 1 to 3 didn't erase the data. It seems that the software starts up with data transfer stuck in the "waiting" mode and will only reset if I unplug the display from the computer, then it allows data transfer, but tells me there is no data to transfer. How do I get that data downloaded?
