Problems with accidental notes, key signatures
I've been working on a score where in the middle of it I change key signature, then return to the previous key signature and then back to the former key signature.
Problem is that the program didn't read quite well the back to the original key signature ( Gm, then G, then Gm again). Sound stayed in G, despite score had apparently changed to Gm. I wrote about 50 bars more believing that key signature changed (as I could see in the score) when actually the sound didn't change.
Now I just realized the program was playing E's and B's with natural sign, I selected all the bars I wanted to return to Gm but it just canceled the key signature in the beginning and not every E and B, to be Eb's and B's.
Is there a way to automatically correct all of this notes (just the 50 bars, not the the entire score)? And not every note manually... It's an error of the program but I just realized too late.

Without the score we can only guess at what might be going on, but it sounds like somehow you entered notes while in a different key signature than you thought you were in, so you entered B's when you meant to enter Bb's or vice versa? As you've seen, changing the key signature does not change the pitches - once you enter a B, it remains a B even if you change the key signature.
If you need to change this, one way is to select the region, hit Alt+Shift+Up to transpose everything up diatonically (within the key), then Alt+Shift+Down to transpose back down. This basically loses all accidentals.
If you download the release candidate for the upcoming 2.1 release, you can also select the region, right click one B, Select / More, then check the "Same pitch" and "In selection" options to select all B's in the range, then hit Down to change to Bb.
