To make that steps and to start using new OS installation we all need old data, photos, music and of course our Emails. With emails – we comes to the problems – and specially if we are using IncrediMail application.

IncrediMail version 2.0 has option to easily migrate from one IncrediMail computer to another one, but this application is so buggy and in most cases all I getting these errors. IncrediMail just can’t transfer data. This is not first time I’m getting in trouble with IncrediMail – and that is good reason for me to try other Email applications.
