I think you can try contacting TAC and ask them to publish an image for you although your contract is expired.
If they refused you may get this escalated and tell them I bought this device and I only need the driver.
try e-mailing firstname.lastname@example.org and write your request. I am no sure if they'll agree on this. you can't even open a TAC case if you don't have a contract but try asking them a favor to publish you the image! not sure if they'll agree (they usually don't but trying will not harm).
What you can also do is to ask a friend that has a contract to download this peace of software for you and get rid of this headache.
