How to recover USB Flash password

Hi,
I bought a TDK 8GB Flash Disk. This flash disk will enable you to partition your files into two. One is without password and the other one is protected with password. I have my important files saved on the protected partition. Everything including important documents and photos. The problem is whenever, I typed my password; the flash disk will have an error box. The error is;

Password error. please try again
Error times: 1/6
There is no way that i forgot my password. But when I input a password, the flash disk asked for a hint. I typed the password and the hint correctly. And yet the error appears. And all I can access now is the non protected partition. But for now, I really need to open my important documents for printing. How can I fix this?
Is there software that can remove the password for this?
I am using it on my Windows Vista Ultimate. I don't want to try another password because I might lose my files when I reached the maximum limit for inputting a wrong password. Can someone here help me?
I couldn't find any support on problems like this in TDK website. Please help.
Thank you.
