avoid non a-z,A-Z,0-9 characters of any kind.
I for example installed AP under normal folders... personal folder was my familyname.... I used german umlaut et voila same result...
Thanks Georg, does it mean that the file can't be nammed with non a-z, A-Z, 0-9 characters? It is the case.
Better than the pic, you can see the result here, http://www.jack-urvoy.com/jazzclubdesavoie.html
In my case it was not the filename itself causing the troubles but the folder containing the imges. foldername had one "à¤" and also spaces...
so your error message shows a path to the files.... do these files exist in exact this named path?
try it redoing the project with characters a-z,0-9 in filenames and paths...
the playbackgroundsound "error" is normal - and if file errors are gone this error will not be displayed anymore. How to solve this (dont know...)
