Did you migrate to 8.0 or 8.10? If 8.10, this uses a totally new licensing scheme, and you are required to obtain new licenses

omnicc -password_info
and re-direct the output to a 'txt' file. If you prefer not to have your password file exposed for all to see, you can send it to me directly using Forum Private Message, or send it to my e-mai;
