Internet connection not available ?

I have been happily using the free version of VDownloader with Windows Vista Ultimate for several years. Recently however, i began having internet connection issues..... with a constantly recurring error "Internet connection not available" followed closely by "Internet connection available" etc.

I have uninstalled/reinstalled numerous times, including clearing out the registry, with no luck.

Is there a free version of VDownloader that still operates with Windows Vista.

Hope you can help - BrownDog
