@Karnstein: *cough* Provide as imp said and it's written in the help-text on the right side...
You will be asked if you want the BWS to run the download for the missing files again (useful if you had a connection problem) or provide them. Providing files can be done by initiating a download with your default web browser. You don't have to know the link, the "BiG World Setup" will open it for you to guide you through this process.When the question pops up, select to provide the mod by selecting a file on your computer.
Your other choice is to select the file, which will open a file-selection-dialog. Browse your disk for the appropriate file and select it. You may also use this to force the BWS to use a file with a name or size that differs from the expected values.Some files could not be downloaded with the "BiG World Setup". Do you want the BWS to try to load the mods again, provide the files yourself (see remarks) or just continue?
