I made it and transfer all my assigned exponents to my new account. To be honest I don't have a clue how I did it. I know I didn't use procedure described in primenet faq.
Also, in the process of transfering exponents I lost one exponent. It doesn't show neither on my old nor on my new account. And I didn't save that exponent anywhere, so I don't know what number it was. Is there any way I can find out what number it was?
/edit - I find what exponent it was in prime.log file. Somehow I unreserve it?!? I didn't want to do that!

Can I reserve it again? Help, please!
