Data Protector 6.0 - How to license BA153BAE

Hello,

we did a new installation of Data Protector 6.0 on Windows Server 2003 in a SAN (EVA4000, MSL4048, Windows Server, VMWare Server). We had no problems in adding the needed licenses. But:
I cannot install the license for BA153BAE - any, HP Data Prot opn File Bkup 10-Srvrs ELTU.

Data Protector does not accept the password and is telling us, that the key is wrong. In fact it has a total different format than the codes for the other licenses.

Any idea?
