Hi,
the first error message is not important: it concerns a small problem
which occurs when calculating the density effect on stopping power when the
material density is very different from the standard one. The problem
is being solved and will disappear in the next respin. You can ignore it
for the time being, since it is not likely to affect your results.
The second error message is clearly due to an input error. But we cannot
find what the error is unless you send us your input file.
I take this opportunity to remind all users to send their input file
when asking about some error or problem.
