Dp 4.5 Problem, Error when beginning Options

[PianoPercMan]

To whom it may confuse:

I have been using DP for a few years. I just upgraded to DP 4.5 and everything went OK when installing and authorizing but when I try to start a NEW file there is a problem.

I have tried to open previous files (DP 4.12) but it errors out and says that this file I am trying to open was created with a LATER version of DP and cannot be opened. The latest version of DP is the one I am trying to open this file with!

Ok, then I tried to start a NEW file and then it says:

An error has occured while writing to the disk. The file name "New File" was not saved.

Try to save your file on another disk or folder or with a different name.

Ok, I have done ALL of that. Then I select CANCEL and the app just quits after that.

MOTU says to just uninstall and reinstall. I done that SEVERAL times.

What else can I do?
HELP!!!
Thanks in advance and let me know how I may help YOU in the future!

Good evening,

Maybe you should consider an update to DP 4.5.1 then to DP 4.5.2.
I'm using DP 4.6 right now, but I remeber I had this kind of problems prior to the update of the 4.5 version.
The updates installer should be available for free from MOTU website. ( www.motu.com )
Hope this will help.

I had similar problems, as well with the 4.5 upgrade. Now, in 4.6.

Assuming that your using Mac, click the "Get Info" in file menu or control click on 1 of your old files/projects and choose "Get Info". Where it says, "Open with...", choose your latest update. From then on, all DP files, old and new should open with that latest update.

To be clear, first open which ever folder and then do the above on an actual DP file within that folder, not just the folder that it's in.

A good thing to do is to keep an entitled log/folder of all your solutions for future upgrade reference.

Hope that helps.
