That specific download was pulled by the developer for quality reasons. Other downloads are unavailable due to them not making it through subsequent virus checks. Any download that shows up as a virus, mostly false positives, are filtered out. However, in general, most downloads should work fine.
If there is a download that you would like to see back you can make a request in the forum or get in touch with the developer through PM. It should be possible to upload any download again but with the virus warning solved.
