Allison,
We have fixed this problem on 6th of April 2016. The new version
should have worked. Please make sure that you are using CLAN version
"V 06-Apr-2016", sometime Windows system fails to install the latest
version even if you instruct it to do so. If you are using the
latest version of CLAN, then one problem could be that the "File In"
button was not used to select data file(s) for analyses. Another
problem could be that file "Negativewords.cut" does not exists by
that exact name or that "working" or "lib"
button in Commands window is not set correctly. Since you are not
reporting the exact error message that CLAN give, I can not be more
specific. If you are using the latest version of CLAN, then after
you run the command below, please copy all CLAN output from "CLAN
Output" window to your email and send it to me. It would be even
better if you could also attach the "Negativewords.cut" file to that
email.
Leonid.
