Saplicense -install DBSLconnect failed with return code 18

We copied our development system on V5R2 to our new

Development system on V5R4 installed.

We restored all cfg- libraries - dlo's etc.

When I go and try to install a new license key on new as/400

I get this error

DBSLconnect failed with return code 18

ANy help would be appreciated

Thanks
