Hi Tarik,
I think I have spotted the problem. The first line in the keys.vf file
does not have a -t parameter. The first line should always be -t 0 and
every line needs to have -t parameter assigned.
rcalc is very unforgiving in this regard. Since your first line did not
match the format it just stopped. It is also very sensitive to trailing
whitespace, thus if you had "-t 0 " as opposed to "-t 0" this would also
cause a problem.
Hopefully this will get you past this piece and onto the next.
-Jack
