Hi Mikl,
I've tried to open your VI, with my LabVIEW 7.1, but only the main window of LV opens (the VI actually is not opened), I don't know why....
Anyway, I normally use the compact flash in my cFP-2020 (similar to 2120), and it works, maybe the problem is with express vi or tdm file management...
About express VIs and embedded cFP applications, I was suggested to avoid them, because in general, they can be less efficient than normal functions. In cFP-2020 (75 MHz) that matters!
Bye!
