Sounds like your command mode has been reset either in Flexi or in the ce5000.
They have to match or it won't work.
Graphtec's can be set from the keypad to switch between GP-GL to HP-GL.
I'd bring it up on the pad and then switch to the other option and see if that fixes it.
Not sure were the option is in Flexi 10 to set the command mode.
Might have to reload the driver for the Graphtec to reset it.
