DM 501_b073 and 501_b084 can't recognize phone and "preparing to install" keeps flashing

Hi there,


My DM 5.0.1 was working fine until I updated it to version 610_b038.


Version 610 had its own set of problems (unable to open) so I did a clean uninstall of 610 and reinstalled version 5.0.1 but now DM is unable to recognize my phone when ever I plug the USB in. Well, momentarily it does acknowledges the phone and the pin but within seconds it disappears and fails to recognize.


And while DM 5.0.1 is open, windows screen keeps flashing "preparing to install"  intermittently. I haven't got a clue what it is trying to install.


I am on Windows XP Pro (SP3).


The DM 5.0.1 file that I have has been tested on my machine before and it is a working copy. But as I mentioned, after 610 everything has gone haywire. As for 610, I have downloaded it from BB site on 3 different occasions.


Any help on this matter will be much appreciated. Many thanks.
