Bronto, i need 'feed' help. respond ASAP!

hi i need your help. i just used your program, and its working great! thanks!
but, when i add a feed and press transmit, most of my feeds stop and say "file to big" then i cant see the feed.

my question is "is there a way for the feed to just show me the first part of the file so i can still see the feed =, or is there a way to download more.

thanks for your help. please respond asap. you can email me at dvd.marc.12@gmail.com with an answer (so i can see it on the ds!) or on he forum, though i would prefer email.
