Sometimes when you run the application it ends up with uploading errors;

An error has occurred in 'FTPClient.Connect' - 'Could not load file or assembly 'WeOnlyDo.Security.Cryptography.KeyManager, Version=, Culture=neutral, PublicKeyToken=900ddd6a51580424' or one of its dependencies. An attempt was made to load a program with an incorrect format.'

This means that the format of the WeOnlyDo cryptography file is not matching to the program and PC format.

This error comes when the assembly version (32 or 64 bit) is not matching to the application version. 

Please check the build version of the app(make sure it is built under Mixed platform)
