Welcome to BVEStation.
Check to make sure they are in the right folder. I think Mr Railfan said that he packaged them wrong, or something similar.
Thx for the advice Let's see if it works. Thx it works now.
The earlier versions don't support the .flac audio format, which is what i use to package the announcement files. Only Openbve 1.4.0 or higher can read the .flac formats.
