got it! i contacted GMAC:
the library is not configured right. To do so, go to:
Tools --> User defined feature --> Configure Library
If there as library loaded, then click on change. If the there is no library loaded the browse window is opened automatically.
for the library definition file, go to the folder UGII --> Folder UDF, and select here the file dbc_udf_ascii.def
For the database file, go to UGII --> UDF, and select or create the file: udf_database.txt
Now the original files should be loaded. And you should be able to bowse through the libraries again.
You can place these files anywhere you want.
Now just go back to NX, and again go to Tools --> User defined features --> Configure library. And now select change, and browse to the files in the new (network) folder.
Best regards,
