This indicates an error in the RTW installation, the 1.2 patch installation, or a leftover from another patch or BI.

Since this problem would affect every single person that installs EB if it were an EB problem (It indicates that an event found in descr_event_images.txt does not exist in the events definitions), and since only a few people have had similar problems, and all solved their problems through a reinstall of RTW and the 1.2 patch, I can safely say with 100% certainty that is is not caused by EB itself, though perhaps a corruption during the download may cause installation errors.
