An apparent idiot about jdownloader

I am a preinum member of rapidgator,bitshare, & luckyshare.
DAP works excellent to download these.As I can't afford every
filehoster, tried jdownloader as a free user. Worked once,but
now linkgrabber does not recognize files to download . Deleted and redownloaded
jdownloader with same probblem.WTH am I doing wrong? BTW I have average
techno savvy , so please don't overwhelm me with technospeak.

It might be faster if you checked this site:
