Fortunately our admin had a backup of the file, so yes, I have the previous version. It was saved on my personal user-share (domain folder), so behind the scenes a NFS synced drive. Saved locally in first place but synced to the domain. I just did some of yesterday's changes again, saved it, and now I can open it again... Seems it was a one-time effect but nonetheless scary that this can happen... Never had this before and I use paint.net for many many MANY years now. I attached the original file and the modified (correct) file here again for now, maybe you can find in a diff what happened. Are there any log files I could send you? somewhere in the appdata folder or so? original.pdn.txt modified-working.pdn.txt

I have a multilayer-file (25+ Layers) where I added some more and hit Ctrl-S Some time later I tried to re-open it and paint.net gives me this DivisionByZero-Exception: System.DivideByZeroException: Es wurde versucht, durch 0 (null) zu teilen. bei PaintDotNet.MemoryBlock.PaintDotNet.Serialization.IDeferredSerializable.FinishDeserialization(Stream input, DeferredFormatter formatter) in D:\src\pdn\src\Core\MemoryBlock.cs:Zeile 643. bei PaintDotNet.Serialization.DeferredFormatter.FinishDeserialization(Stream input) in D:\src\pdn\src\Core\Serialization\DeferredFormatter.cs:Zeile 141. bei PaintDotNet.Document.FromStream(Stream stream) in D:\src\pdn\src\Data\Document.cs:Zeile 1443. bei PaintDotNet.FileType.Load(Stream input) in D:\src\pdn\src\Data\FileType.cs:Zeile 495. bei PaintDotNet.Functional.Func.Eval[T1,TRet](Func`2 f, T1 arg1) in D:\src\pdn\src\Base\Functional\Func.cs:Zeile 158. The file is no secret, it just contains android and apple logos - we compose avatars for our testing system out of them, so I attached it here to make it easier for you to reproduce. Unfortunately this forum does not allow to attach .pdn files... wtf? ? I renamed it to .pdn.txt and I hope you can get it binary correctly. You have to change the extension back to .pdn device-avatars.pdn.txt
