I accidently removed the lock on my memory stick…help?

My maxell memory stick comes with a lock so that you have to put a password in to view your files. I stupidly deleted the lock program though so now I have no way to access my files! What can I do? I really need to access them for a presentation I have at uni in an hour.
Erm the memory stick is a maxell and the lock thing is called LOCKv100 version 7.

:/
No. its really confusing :( It has about 3 different “devices” in it. Stupid thing!
