When you install a new server environment, you should simply create a new reseller.

The option to type a reseller id should only be used if you have been given one directly by a RushFiles employee, or if you prematurely had to close the installation program, in which case the field will be automatically filled. 

The reason for this is that if you use an id you have used on our demo servers or from previous installations, it can cause serious problems and issues with the new installation.
