The empty file (0 bytes) is rolltreppe.evt. I used FTP to download premetro island station,<kuid:112820:26025>
from the DLS, then loaded the .cdp file into TRS2004 (without error) so I could see the individual files. Found the empty file, deleted it then used TS2010 CM3.3 Import Content function to import it. It commited without error. If you don't have TRS2004 but do have TRS2006, you can use CMP to import the .cdp, then open it for edit, delete rolltreppe.evt, save and commit. Now open for edit to import into TS2009 or 2010 or make a CDP file then import that into TS2009 or 2010.
