MS Access “How to Get Access” Question

Hi everybody:

I purchased a software that uses MS Access. When I installed it on my computer initially (in 2004), I used the word “administrator” as my password.

Earlier this summer my computer semi-crashed and I bought a new one. I transferred all my files to the new computer.

When I tried to open my file (from the old computer), it wouldn’t allow me to because it said I need administrative rights (I’m thinking that old password which it automatically bypasses for whatever reason).

How can I fix this?

Thanks!
