I mean that I regularly clean the registry, that's all. Sorry for the bad explanation, I'm not good at the English language.
Meanwhile I use a webmail with the same email name.
Thanks for the possible solution to the problem, I will try it tomorrow now and let it now.
When I cleaned register I can't no more activate a link in a opened e-mail message. This was already done with c cleaner free same version, some versions previously there were never problems.
