For me it's parts 1-4 of the "00 X S C E C F B T M B A B 00 X Part1 rar" series of files.

I just receive site cannot be reached after clicking the download button for the second time (after the pop up ad). I've tried several times over the last 3 dayswith no success.

Other links in the index still work so it seems that maybe these links specifically have an issue.

Have you been able to download?
