Sprint Nav glitch or what?

[HBOOT]

Hey fellas:
I have been using Sprint Nav since the new Rom 3.35 upgrade came out and all was cool. All of the sudden today,when I hit "type it" to enter the destination , the application goes away like if I "xed" it out. Anyone experiened this prob please share.
I am running stock 3.35 with many progs but none was installed recently. Thanks again.
By the way my subscription shows expiration date of aug 31, what's the deal with that? Sero here.
