First off, before you can obtain any software, you not only have to set up an account but you must summit signed license agreements and have them in your file.
If you have all of that then you should be good to go.
To see what software that you can currently down load, open your MOL account, then highlite resource center, click on resource center, this will take you to a page that on the left side you click on the section you want.
Now, click on software, then click on two way, and it will list what is currently available to you. If there is nothing here, then you have never order any software.
In order to purchase new software, go to the top of page and highlite buying center, then click on search catalog, then if you know the part number of the software (HKN4123), enter that and it will allow you to 'order' and usually within a couple of hours you can find it over on the resource site and a CD will also be mailed to you.
You can also go to case management and summit a request for the part number, just tell them you are looking for the software for X radio, and also tell them you under stand that there is a PDF of the software matrex and request a copy.
Good luck
