Is there a specific reason why you moved TO GoDaddy? For example, they gave you a summer house in Florida for being their user?

Unless you have a VERY good reason to be their user, you should run away like crazy and switch to a GOOD host. GoDaddy is everything but a good host. They are OK for running simple plain HTML sites, but they are a disaster for running an application like Zen Cart. I had a client using GoDaddy's dedicated server and his site was slow as hell. When I finally managed to get him to transfer to a decent host, his site got almost 10x faster. And he switched to an entry level VPS with that host (BTW, it cost 5x less). Of course, all of his other hosting problems were gone as well.
So, to sumarize - GranDaddy is great for DOMAIN registration and management, but that's it. Do not, and I repeat, DO NOT use them for hosting anything more than a 5 page simple HTML site...

Trust me on this one. I believe just about anyone who knows something about Zen Cart will back me up on this...
