Netware open file option install trouble

Hello. I have Symantec Backup Exec for Windows Servers with Backup Exec Remote Agent for NetWare Servers. When I buy license resseler says (Symantec Russia), that Backup Exec Open File Option for Remote NetWare Servers now is part of Remote Agent for NetWare Servers and not sold. I have license key for Remote Agent for NetWare Servers. When I install Remote Agent for NetWare Servers with "open file option" enabled it asks me for license key. I enter my key, but it says, that key is wrong! I tryed to upgrade license to 12.5, got keys. Install 12.5 version, but new key is wrong too. What I did wrong? P.S. Exuse my english.
