Noobie question?

ok…so the eclipse IDE plugin either cant find the main type or else it cant find something called Predef$…i looked it up on stackoverflow.com & none of that seemed to work either…

OTOH, when i attempted to download the SBT from intellij it just turns forever & soon afterwards the whole system crashes…

so i guess my ? is how im supposed to use this when it seems like theres always something missing?..

thx…
:v: billy…
