RAR Passowrd

I have an incredibly important document in a RAR file that is password protected. I wrote down the password and kept it in my wallet, but my wallet got stolen and as the document is more that 2years old I have NO clue what the password is…I have tried some free software, but to no avail…I am not sure how long the passowrd was, which characters were used…

Is there a program out there that can run through passowrds quicker than the free ones? I am going away for 3weeks and can leave the computer running for this entire time…

Thank you, it’s really important to me…
