I guess: Did you choose a skin? I diddent return a correct error. I fix that now and upload another exe file.
[EDIT] Tried to install and just added a album directory, and then save it (I leave all other as they was). It works fine here.
I do not known why, because i diddent got that message. Do you have the config.dat file?
[/EDIT]
I have again uploaded a new zip file (same name).
