Can't import openvpn certificates from pfsense 1.2.3 to pfsense 2.0

How to import certificates from pfsense 1.2.3 to pfsense 2.0?

I copy ca.crt and ca.key to system -> certificate manager - CAs certificate data and certificate private key, then server.crt and server.key to  system -> certificate manager - Certificates.

Use OpenVPN Settings:

*Remote Access (SSL/TLS)
*UDP
*tun
*Peer Certificate Authority (name from certificate manager)
*Server Certificate (name from certificate manager)
*DH Paramether  Length 1024 bits
*Encryption BF-CBC128
*Certificate Depth Client+Server
*Tunnel Network 192.168.55.0/24
*Local Network 192.168.2.0/24

When Connecting OpenVPN Client, I receive error:
