Thank you for the informations:

1. Validation tool says that you are missing patch_1.pak (or something similar)? Get this file and extract it in <RTW>/data/packs. [ftp://ftp.europabarbarorum.org/patch_1.zip]

2. I see you Rome-TW.exe is changed, are you using a crack or similar? EB won't work properly with a changed exe.
