Error #0175: the Portable MyChat Client (XXX) and MyChat Server (%s) are incompatible

 

Error

A client and server applications are incompatible, and you have to use the same versions of MyChat Client and MyChat Server.

 

Problem solution

MyChat Client Portable version can't be updated automatically. You must update it manually.

 

If MyChat Server is older than MyChat Client, then you should update your Portable MyChat Client to the version that mathches with your server. If the server version is older than MyChat Client Portable version, then you need to update the server or install the client with the same version as the server.
