I have installed and run an app (on S60 v3 device) from the past 10 days, everthing was working fine. But now I'm not able to install. I'm using protected UID (0x2xxxxxx) and a valid developer certificate (which expires in Dec 2006). The installer progress bar goes all the way till the end and then it complains saying "Unable to install".
I tried getting a new protected UID from Symbian, changed the vendor name in pkg file, but still it says "Unable to install". Recentlly I formatted the memory card and tried installing, but all in vein.
Any idea what the problem could be ?
