A few months ago, I had a very sudden and strange thing happen to the QuickGPS app on my Windows Mobile HTC Touch Cruise smartphone.  My GPS signal would take forever to get a signal and when I opened QuickGPS and clicked Download now I got the error “Connection failed. Please try again later”.  Needless to say, later didn’t help. It also said:

Download time: Not yet downloaded
Valid time: Expired

It happened if I was connected over 3G, GPRS, or through USB/ActiveSync. All other data networking is fine.  But nothing worked.   After many hours of googling I found this page. Basically, for some reason one or more of the phone’s registry settings are busted and need to be fixed (at least it was in my case).  I grabbed an application that let you edit the registry on the phone and then verified these registry settings – and my problem was fixed!

[HKEY_LOCAL_MACHINE\Software\HTC\QuickGPS]
"RemindTime"="02151010034724"
"Bias"=dword:fffffed4
"ExpiredTime"=dword:00002760
"folder"="\Windows\"
"region"="US"
"INIDate"="20060531"
"remind"=dword:00000001
"actSync"=dword:00000001
"auto"=dword:00000000
"NotifyID"=dword:00001960
"INIFile"=""
"path"=""
"EEFile"="xtra.bin"
"curRegion"=dword:00000000
"curIP"=dword:00000000
"pwd"="1"
"authname"="1"

If editing the registry doesn’t sound like your kind of thing, someone in the forum of the above link has a cab file that makes the changes for you.
