Error loading Nuvi 1450 and custom POI Software

I have a Nuvi 1450, and I tried the loading custom POI software in it. It has been working fine for several times now until I get the following error when I try to load the software. I have attached the screenshot below.
I don’t have any idea what changed and why is it happening.
I would gladly appreciate your help towards my problem.
