Sftp Download - Out of bound Array exception

Question

Hello. I'm attempting a bulk transfer using the Download method and am experiencing a similar exception to what's outlined in this string: (http://forum.rebex.net/questions/2613/sftp-getfiles-throws-index-out-of-the-bounds-exception).

I'm able to successfully perform individual file, NonRecursive, transfers, ie:

client.Download("/cms/cmstables/chr0721", @"c:\sftp", TraversalMode.NonRecursive, TransferMethod.Copy, ActionOnExistingFiles.OverwriteAll);

however when I attempt a recursive, matchFilesShallow, or matchFilesDeep transfer, ie.

client.Download("/cms/cmstables/*", @"c:\sftp", TraversalMode.Recursive, TransferMethod.Copy, ActionOnExistingFiles.OverwriteAll);

the following exception is thrown:

System.ArgumentOutOfRangeException was unhandled
  Message=Index is out of the bounds of an array.
Parameter name: created
Actual value was 12/31/1969 4:00:00 PM.
  Source=Rebex.Sftp

I'm using Rebex SFTP for .Net 2012 R1 (Trial Version). Anyone have any advice?

thanks, brad

UPDATE: This is fixed in version 2012 R2

It seems to be the same issue as you mentioned in your question. The answer of Lukas Pokorny should work for you too:

This is caused by a bug in a workaround for servers that return invalid (zero) date/time values (such as FreeFTPd). A hotfix is already available. Please download it from one of these URLs and give it a try:

Rebex SFTP - Hotfix Build 4527 (for .NET 2.0/3.0/3.5/4.0)

Rebex SFTP - Hotfix Build 4527 (for .NET CF 2.0/3.5)

That worked perfectly. Thanks Lukas.
