Replay Music 2.51 co-existing with Replay Music 3.55

Will not work with Vista operating system.

Developer said
Yes, he can try Replay Music
2.51 to see if he gets better recognition. However, if he has Vista it will
not work. Only RM versions 3.0 and greater will work on Vista. So, if he
doesn't have Vista, he can just install RM 2.51. No need to uninstall RM
3.55. He also won't need to re-enter a new registration code for 2.51, as
his code should work for both versions.
