Here is a preview of the answer. Basically, you need updated daten files.
for ISTA v41 Daten Files (or something like that). You can find links to them by searching on ********* dot com or on other forums. Once you download the updated daten files and copy and paste them with the old files (oh and run the laden.bat program file) you will just need to recode the KOMBI. Some people say flash a blank .man (but I didn't do this because it's not needed...simply recode with new daten files). Hope you find the fix to your problem...good luck!
