Have you double checked that the settings and verified that the alert can be heard (file is not missing)? How are you modifying the settings?
So a little background on my situation...
I have 2 emails, my blackberry.net email and my Enterprise account email.
The settings I currently have for my Enterprise account email are Vibrate + Tone. This is for "Out of Holster" and "In Holster", both settings the same. I have this under my Profiles - Normal
My current tone is Notifier_BBpro_5 which I can play in my Media player, therefore don't believe it is missing.
Also note that the phone doesn't even vibrate when I get a new email.
To change / verify my settings I am selecting the "Profiles" on my desktop and then go to Advanced and select Normal (Active) and then select "Messages(Desktop)" for my Enterprise account.
I plugged in my Blackberry into my computer yesterday and installed the CD that came with my package.
After going through some security options I noticed that it had added "[email protected]" (which is not my Enterprise nor my Blackberry.net) as one of my emails on my phone.
I never asked it to do so, could this be the cause to all this?
I do have GMail notifier on my desktop with the email mentioned above but how would it have imported??
It could be. If you selected the incorrect connection when installing. Uninstalling and reinstalling making sure you choose the BES option and not BIS.
