Please enable Verbose Upload in settings, try it again, and then copy/paste the full text of the error message here.
Hard as this may be to belive, error messages contain information - we need to see the whole thing.
Also, what board are you uploading to, and what version of the IDE? If it's 1.6.6+, consider trying 1.6.5r5, that one seems to work best from recent releases. The three subsequent releases (1.6.6 ~ 1.6.8) have had serious enough bugs that I can't recommend them.
Has the board worked before, or is this the first time you've tried to use it?
