Now, in my results list I see nine tasks. But on my computer - only six! BOINC 5.2.2.
What I should make for receiving this tasks?

I have this feature in Einstein@Home and "beat it" installation of BOINC 4.45, which refresh tasks list.

But I can not using BOINC 4.45 in this case because i don't receive Account Key and join to project in BOINC 5.2.2 on login(e-mail) & password. When I unistall 5.2.2 and install 4.45 it show me a error message about attaching to project with account key.

I not sure on 100%, but in other situation, when I don't receive message from CPDN support of e-mail server say me that problem consist in not full conformity of server that send message, to SMTP standards.

Excuse me please, if my English is not right. :)

If I understand you correctly, you are saying that when you look on the project website, you see more work units issued to you than you actually have on your computer right now.

The website will show work units that you've completed, as well as those that are in progress. So, perhaps you've already completed 3? Looking at the website, it looks like you've now got 5 work units completed with "success", one that had an error, and there were three that didn't get completed prior to their deadline... oh and it's in reverse of the order they were downloaded to you, so those first three work units that you downloaded on January 3rd, were not reported back to the server before their deadline.

There's nothing you can do about them now. So I wouldn't worry about it.
