IMHO, you need to change In FlashBuilder.ini file the language locale from fi_FI to en_EN
Hi, thanks for fast reply.
Unfortunately I already tried that with no success. The strange thing is, that in my Flash Builder plugin directory in eclipse.ini the language was already declared as follows:
Didn't even touch that, it was there before and still my errors and warnings were (and still stay) in Finnish (everything else in Eclipse is in English).
Change FlashBuilder.ini if you are on standalone and try:
Window -> Perspectives -> Reset Perpective.
If that doesn't work, try switching to a new workspace.
