Strange error after latest update

[SirNasso]

Hi guys.
Tonight,after Miranda said there were updates fot it and I let it do them. But now this error shown on the attached picture is showing up on launch.Have no Idea what it says,as I don't understand german.So can you help me with it? Tried restoring it from a backup,but after the update the result is the same.
It was working fine before the update.

Fixed already. It’s getting harder to maintain the database driver under shitty Windows XP...

[SirNasso]

Well I'm not using XP.But you are saiyng this thing is fixed and I should try to update again?

[dartraiden]

What is your operating system? We fixed the database driver starting under Windows XP. We don’t know about problems in other operating systems,

I have the same issue on Windows 10 1909 x64 using Miranda NG 0.95.11 alpha build #22354 (c4b49b47f8).

[dartraiden]

This is strange, because developers use Windows 10 x64 too... Anyway try to update

This error means that the database driver did not start and Miranda cannot read the profile, therefore, it believes that profile has an unknown format

[Chol]

Hmm, update to what? Looking at https://github.com/miranda-ng/miranda-ng/commits/master my c4b49b47f8 seems to be the most recent version.
Are the previous builds archived somewhere? I would like to downgrade to yesterdays build to see if it works again.

[dartraiden]

Backup your current profile (C:\Users\username\AppData\Roaming\Miranda NG by default) and try to create new profile. If this succeeds, then the problem is in your profile, if unsuccessfully, then problem is in the database driver.

Previous versions of binaries are stored in <Miranda path>\Plugin Updates\Backups

I'm using Windows 10 Pro 64bit

[dartraiden]

I'm using Windows 10 Pro 64bit

Please try this too

We need to find out where the problem is: in the damaged profiles that opened on the new driver or in the driver itself.

[Chol]

With a new profile, the application starts.
I restored my profile from a backup from yesterday morning, when the application worked. This profile does not work now with the current application.

[Chol]

I just started the stable version ( https://www.miranda-ng.org/distr/stable/miranda-ng-v0.95.10.3_x64.7z ) with my profile. This works.

[dartraiden]

Thus, some profiles (for example, I didn’t have any problems) that worked on libmdbx before the update contains something that prevents them from opening by updated libmdbx.

https://github.com/miranda-ng/miranda-ng/issues/2140

Use the stable version until we find and fix the problem.

[dartraiden]

Tomorrow, the developers will look at this and maybe ask for details

[Chol]

Okay, replacing
Miranda NG\Libs\libmdbx.mir
with the backup from
Miranda NG\Plugin Updates\Backups\Libs\libmdbx.mir
also fixes the nightly version for me. My profile is very old, I am using Miranda IM since 15 years or so.
