Backup doesn't work

I was supposed to contact support and include this info. 

    System.IO.IOException: database disk image is malformed —> System.Data.SQLite.SQLiteException: database disk image is malformed    at System.Data.SQLite.SQLiteBlob.Read(Byte[] buffer, Int32 count, Int32 offset)    at MailClient.Storage.Data.BlobStream.Read(Byte[] buffer, Int32 offset, Int32 count)    — End of inner exception stack trace —    at MailClient.Storage.Data.BlobStream.Read(Byte[] buffer, Int32 offset, Int32 count)    at MailClient.Streams.StreamHelper.CopyStream(Stream inputStream, Stream outputStream, Nullable`1 cancellationToken, ProgressReporter reporter)    at MailClient.Storage.Data.DatabaseCopyTool.CopyContents(Table table, Boolean sortDesc)    at MailClient.Storage.Data.DatabaseCopyTool.CopyTableData(Table table)    at MailClient.Storage.Data.DatabaseCopyTool.CopyInternal(String specificTable, Boolean copyIndexesViewsAndTriggers)    at DbBackup.FormBackup.Backup(CancellationToken cancellationToken)    at DbBackup.FormBackup.<mainform_load>b__27_0(Object a, DoWorkEventArgs b) at System.ComponentModel.BackgroundWorker.OnDoWork(DoWorkEventArgs e) at System.ComponentModel.BackgroundWorker.WorkerThreadStart(Object argument) Data: Table: LocalMailContents

Please note that the last time I contacted EmClient because it crashed no one responded to my email…</mainform_load>

Hello Diana,

I am sorry for a late reply,

From what I see from the log, your database is most likely corrupted.

Please note that you have to close eM Client before making any changes in the database location, proceeding without closed eM Client can cause the program crash.

In case you have all your data saved on servers you can simply rename the database folder and start eM Client.
It will create empty database where you can set your accounts again. All your data should be pulled by eM Client automatically then.
You can find eM Client database here: C:\Users%Current User%\AppData\Roaming\eM Client
To locate AppData folder you need to view hidden folders in Windows:
Then just rename the folder and starting eM Client will create a blank database where you can set your accounts again.

In case that you have an account set as POP3, you can restore the old database backup if you made any in Menu > File > Restore
