Have installed our new inventor 6 series licenses.
workes fine for inventor 6, MDT 6 return an error
(error 1.5-18).

the log file says:
14:10:38 (adskflex) UNSUPPORTED: "40900INVBUN_5_0F" (PORT_AT_HOST_PLUS ) bblqk65@EAN005069 (License server does not support this feature (-18,327))

my lisence file does not have this feature:
INCREMENT 42800INVBUN_6_0F adskflex 1.000 permanent 8 \
VENDOR_STRING=commercialermanent SUPERSEDE DUP_GROUP=H \
ISSUED=8-nov-2002 ck=155 SN=700-50700295 SIGN=F0BC14CCC816

Any suggestions?
