I can't take credit for this, found it a while back, but I also like pnp and this has helped alot.
to fix this properly
mirc/script/first.mrc
replace line 258 : mkdir SCRIPT\TEMP | mkdir CONFIG | mkdir THEMES
with : if !$isdir(SCRIPT\TEMP) { mkdir SCRIPT\TEMP } | if !$isdir(CONFIG) { mkdir CONFIG } | if !$isdir(THEMES) { mkdir THEMES }
Hope it helps!
