I have a problem similar to some others in this thread, but I have spent hours on this and still have not been able to resolve the issue.
I have a sprint everything data plan that includes unlimited sprint nav. I used the program on my touch pro without issue. I received my tp2 less than a week ago and immediately flashed a custom rom (caulkin 21888, 2.5....great rom). When I tried to setup gps through various sprintnav cabs, it would work immediately upon install (after entering my name and email addy), but if I close the program down and then launch, it will ask me to subscribe on either a daily or monthly basis. If I attempt to subscribe, I receive messages that either state sprintnav is not available or my purchase is not valid. I am not able to proceed. If I attempt to use telenav, I receive the "...expired, please call telenav..." message. I since flashdanced and re-loaded the stock rom and had the same problem. The sprintnav tab worked the first time I tried it, and after that it asked me to pay and won't allow me to proceed (even if I agree to pay). I should also note my wife is on a samsung moment android phone and her sprintnav works fine, so this issue is specific to my phone (or phone line).
I have seen that if I go into the sprintnav folder and delete the "preferences" file, I can then launch the program and it will ask me for my name, etc. (like a fresh install) and then I can use it one time (until I close it out). Then a new preferences file is created and I have the same issue. If I am desperate at least I can force a way into using the program, but obviously the constant process of deleting a file, logging back in as a first time user, etc. is not ideal.
I looked up my acct at the my.telenav.com website, changed my pin (didn't help) and while on the site I found an account history that shows my last "purchase" ending in mid January. It seems that the way telenav works with Sprint, sprint customers are viewed as month to month telenav customers and there must be some type of communication between the companies to provide the ongoing service. As one might imagine, when I called telenav they told me my acct was expired and I need to contact sprint to re-activate. When I contacted sprint, they told me that doesn't make sense and that they are going to open a trouble ticket and have an engineer check cell towers in my area because it sounds like the towers are not communicating with telenav (yeah, like that is the problem...what a waste of time).
I know this is very loooooong but I was trying to provide as much detail as possible to see if anyone has been through this and can point me in the right direction. My guess is someone at telenav or sprint needs to do something for me, but they don't know what that is. Maybe someone here can tell me what to tell them
Any help is appreciated...thanks.
