Sandbox To Live

I installed the plugin and tested with a Sandbox account and everything worked great. I switched to the live mode, updated the credentials. This did not work in that when I clicked proceed to paypal it always took me to the sandbox account. I purged the cache and it still did not work. I deactivated the plugin but when I re-enabled it the settings were still there so I suspect the settings were not cleared out. I do have a business account with paypal, so I am asking for help now. I have not uninstalled/reinstalled the plugin yet. Any help or guidance would be greatly appreciated.
