I'm facing problem using Desktop Manager 4.5: I wasn't able syncing my 8320 with my organizer data since i wasn't connecting to the internet. When i used Desktop Manager 4.2 i could connected anytime without internet connection.
Anybody can help me with this? Thanks!

sathe, welcome to the BBforums.

Click CANCEL on the update, or let it time out. It will.

And then proceed.

or you can always downgrade back to 4.2 or 4.3 DM.

Good luck.

If I download Destop Manager 4.5 before I put DM 4.3 on my computer will I have any problems.

I'm guessing you mean "install" and not "download".

There's no issue with downloading. As for installing -- just make sure you first uninstall 4.5 completely. I recommend looking for the "clean uninstall" instructions and rebooting before installing 4.3.
