As you may be aware, Adobe Flash is old technology which has been abandoned by mainstream developers. Hence why you may run into some issues when trying to use The Belle and Sebastian Flash Collection. This page should help you troubleshoot any common issues.
If you're unable to begin downloading, try right-clicking on the download link and selecting 'Save Link As...'. Once that window opens, refresh the page and the download should begin.
If your browser blocks the download and tells you it might be unsafe, then you can safely bypass the warning and download it anyway. Depending on which web browser you use the procedure for bypassing the download warning may look different.
On Windows, your computer will automatically assume that any Adobe Flash software is unsafe and will prevent you from opening the program. The Belle and Sebastian Flash Collection however, is completely safe to use. You can bypass this by clicking 'More info' and then the 'Run anyway' button.
