I have been in a similar situation and got out okay by trial and error. 
I know this isn't much help to you now, but in my case I had a sentence 
as my password. Once after a looong time I tried it and it didn't work. 
It was just a matter of recalling the correct words ending with the 
right punctuation mark. It took me a few tens of tried to get it right 
-- I knew the meaning of the sentence so it wasn't that hard. So, next 
time, instead of a characters, try a sentence; it is much easier to recall.
