I DID IT!!!!! The problem was in my ebay's account details. So here in Russia we have three words in our name like: 1st NAME, SURNAME and 3d NAME(patronymic)... Thus in my registration address I wrote 1st and 3d name in one field. After i delete it and left only 1st and 2nd name and then click "Link my PP account" it worked as it should!!! Fantastic! So check your registration info and account detials for inappropriate symbols, wrong constructions (like 2 words in a filed supposed to has only one, my case) etc. Good Luck!
