Try removing any custom .pk3 files and loading a "pure" q3 instance to rule 
out any bad shader, texture or model files that could be using the same name 
as something in the map you're having problems with.

to simplify, make a new text file in your baseq3 folder with the following 
lines:

rename *.pk3 *.pk
rename pak*.pk pak*.pk3
rename ra3map*.pk ra3map*.pk3

save the file, and rename to makepure.bat and double-click the file you just 
made.  Then fire up ra3 again and try to load the map.  If you're still 
having problems post the error message here. If you aren't having the 
problem any more, the problem lies in another .pk3 file somewhere in your 
baseq3 folder.  At that point, start renaming the .pk files back to .pk3 a 
few at a time (if you have a lot of them I'd do something like 5 at at time) 
until you find the error pop up, then you have to rename the one(s) you just 
renamed back to *.pk one at at time until your problem disappears.. the last 
one you rename that allows you to load the map without errors is the 
culprit - either look for and updated version of that map/model/whatever or 
just discard it and live without it.
