Why am I getting the "EDBClient: Mismatch in datapacket" exception?

I'm often getting this exception "EDBClient: Mismatch in datapacket" when I call ApplyUpdates on a particular ClientDataSet.

I can't reproduce on my machine and I think it started after upgrading to Delphi 2010, because this code is untouched for a 开发者_JAVA百科long time.

An additional information is that I don't use midas.dll, I compile MidasLib unit with my project.

Thanks for any comments.

Check midas.dll version
