Oh dear, I subscribed to various newsgroups at the same time and let it roll overnight i.e NewsPro to go and get headers for all of them. The next morning, my PC was suffering with hypothermia and had frozen with a message; 'Database is too large.....bla bla bla' and had stoppped getting new headers...

I am BRAND new to newsgroups so can someone tell me if this is the right choice or software (I mean better than others!) to use for this purpose? I am expecting sincere answers I mean the truth!!!
