Robbys 1.40 version reads the rrtms.ini in the plugins folder (in theory) (he has used app.path which could mean it will try to read a rrtms.ini in RR's root path.)
Also if you are using Win7 unless you run the "RRTMS Config.exe" as admin it may not be able to write the new settings to rrtms.ini
*edit
I also notice the orginal plugin likes the ini to have spaces after the keyname (not sure whether it is important) but check for that also.
ie
PHP Code:
[UNITS OF MEASUREMENT]
Pressure =2
Temperature =1
as opposed to
PHP Code:
[UNITS OF MEASUREMENT]
Pressure=2
Temperature=1

You could always try my updated version in the first post.
