Missing Collection issues

Recently, when I open (or go to sync) my collection (desktop/PC/Windows10) it shows me the following error messages
see screen shots attached



I am always having to re upload my collection which takes forever as I have quite a large (20k+ albums) collection.
I’ve tried to use backup

I am wondering if there is something wrong with my version of the software or I’m doing something wrong. It has worked a treat for 18 months now so this is fairly recent change. Frustrating.
All help much appreciated. Thank you

Hi @NathuLal ,

When you get the error and restore the data, I’m seeing this at the top of your screen:

note that it says “New Collection”.

I’m getting the feeling there might be some kinds of rights problem where the program isn’t getting enough rights from Windows to operate efficiently.

Here’s what I’d like for you to try:

  1. Close the program if it’s open.
  2. Right click the shortcut to your Collectorz program and then select “Properties”.
  3. Click the Shortcut tab.
  4. There, click the Advanced button
  5. Tick the “Run as Administrator” box:
  6. Click OK and you’re done.

Now, if you get the “corrupted message”, make it open again, until you see your data. Do not sync yet.

Use File > Save Database AS, and save it with a new name in a location you will remember.

You probably want to store it in Documents > Music Collector (not the backup folder).

Now, close the program (do not sync).

Now, open the program again. Does it correctly open your database now? Or do you again get the error?

Yeah Hi . DIdn’t really work. It imported thousands of single tracks from across my collection before I cancelled.
I’m trying a new database imported (XML) from Music Connect

Hi again,
One problem is I have so many differently named collections and back ups of same.
When I followed your instructions using the same collection name as on my Mobile App this is what happened.


so everything this there but it seems I now have to sync from Desktop again and that means I’ll have to resync on the mobile again. Is that correct?

If your Windows version now has the correct data, AND you are able to close and re-open the program and that exact database opens again (please double check this!) then yes, that is what you need to do to keep it working again.

On your computer (after you’ve verified what I wrote above) do this:

  1. Go to menu CLZ Cloud > Synchronize
  2. Click the “Clear CLZ Cloud” button bottom left and confirm.
  3. Now sync with CLZ Cloud to upload all your data to the CLZ Cloud again.

On Mobile:

  1. On any mobile devices where you use our CLZ mobile app:
  • Tap the menu top left and tap MAINTENANCE, then use Clear Database,
  • Then choose Sync with CLZ Cloud to download a fresh copy of your data from the CLZ Cloud.
