Where can I find free orchestral scores?

Did it have orchestral scores though? I mainly downloaded piano sheet.

Oh yeah! It had all the Beethoven symphonies, lots of Haydn and Mozart symphonies, Brahms and Schumann (and concerti by all of them too). It had loads of piano reductions of these scores, mainly because they are easier to scan, but there were also orchestral scores (btw, those names aren't the only ones which had orchestral scores - before it went down it listed some 1,000 composers )
