v6.0rc8 not work OpenVPN

first of all apologize for my English, is a translation of google, and I’m from Argentina.
After updating to version v6rc8 in the openvpn server settings, I get the certificate configured not, when you select the combobox I get the error “could not change ovpn (6)”

dear,

its better to use 5.X not rc

rc8 has problem with certificates, try rc8 or back to rc7

Thank you very much, and I found the thread with the RC9 works well the issue of certificates.
