Litecoin Wallet.dat passphrase lost

Hello Guys i remembered yesterday that i have a wallet with 10 litecoins somewhere on my dropbox account.So i installed the litecoin wallet program i managed to load the wallet but i have a big problem,the password isn't working. I remember what the passord is but it doesen't works. I am a newbie with this hashcat and i don't know exactly how can i set to brut force my password. I made a file with some posibilities versions of the password but they are wrong. If somewone could help i will apreciate and i will make a donation if it will work.

Thanks a lot.
