I suspected it. This will work:
1) go to
http://www.bsplayer.org/
2) click on "download"
3) check "I accept the terms of this license agreement" box
4) select installer or zip
5) click on "download"
6) you will see page saying
"Your download should start automatically in a few seconds...
If your download does not start, click here."
Wait until it asks you where to save the file
7) cancel it
8) the "here" word is a link. Right click on this link.
9) copy it's location to clipboard. It will be something like
http://blah.bsplayer.com/blahblah/bsplayer100.812.exe
10) in that link change 100.812 to 100.811, so it will look like
http://blah.bsplayer.com/blahblah/bsplayer100.811.exe
11) open changed link in your web browser
