Unfortunately Windows did an update on my PC last night and restarted the system. That always means my IDeA-tree where Aquarium was working on, gets corrupted.
Now I try 'restore tree' but nothing seems to happen. I have been waiting now for 2 hours, but it still says 'restoring tree'.
How long do I have to wait before a tree of about 200.000 positions is restored?

Do it mannually .

How do I do that?

Delete the tree file.
then it will empty. Then do add results from the tree.
then do minimax.

Hm, ok, I did that, but the result is a small tree with 'holes'. Some branches disappeared.
Also the evaluation isn't consistent anymore: the best move for white gives +1,05 but the black answer is only '+0,63'.  That should be 1,05 as well.
Then I did another minimax and now it's still minimaxing for more than 15 minutes. How long will this take?

Maybe I didn't delete the right file, so the problem remains.
Which tree exactly I have to delete and where can I find it?
Thank you in advance!

The same tree with the project name u r restoring.
there will be 4 or 5 files with that name. 2 files and 2 folders. Delete them.

I may be stupid, but after I just deleted all the folders with this project name I can not 'add results' from tree anymore. Probably because I just deleted them!?
Wait! I found a folder with the project name I didn't delete (in the folder 'results'). Now I see something happening: a copying process which takes about 8 minutes.
Now I minimax...
and after some while I have my tree back!
Thank you very much for your help!

P.S. Why is Aquarium so buggy all the time? It's a wonderful analysis tool, but very user unfriendly. When I buy an upfate (Aqurium 2019) I have to manually all my files to it. Why not just update like other programms without all the copying stuff?!

That method is to be used when restoring tree does not work.

Aquarium creates "backup" files all the time.  I hope you did not delete them.

Rather than delete anything, I think you should have searched for the backups and copied them over the broken files, thus replacing them.  You can probably still do that.  Look thru the backups to see if you can find something dated prior to the loss.

Use the Windows search function, it is your friend.  It will help you locate all the backups and the current files.  Usually when I do this, I think there are 3 or 4 data files and 1 xml file.  If you can, restore them all from backup.  Aquarium is very good about making and saving multiple layers of backup... so you are safe as long as you haven't deleted them and you haven't managed to fool around so long that Aquarium has backed up over the top of all the backups.

In the end though, 200k node tree is just time.  Probably about a week's worth of work on most machines.  I would be tempted to just start a new tree fresh (I often do that anyway, because large trees tend to get a little convoluted and gone astray).

Ok, Thank you for your advice for future prolems.
Plan B was indeed to start a new project.
