Cannot connect to db after WAS 6.40 Sneak Preview Install

Question

At one time I had the 6.20 ABAP test Drive and the 6.30 Java NW Dev. Stuio installed on my system.  All was fine, and they lived in harmony.  Windows services showed services for SAPDB: J2E and BSP (and a bunch of other SAPDB: servoces, too: CSAPxxxxx, e.g.).  I am now trying to insatll the 6.40 ABAP stack.
I uninstalled the Java 6.30 NW DS system.  (I see that the SAPDB J2E services are still there - what's up with that?)
I installed the 6.40 ABAP stack with no problems whatsoever.  I secured a license from Walldorf, and now I'm trying to install it.  When I run saplicense - install from a CMD window, I get the following error:
DBSlConnect error - RC = 99
SQL Error 709
This error occurs whether I've started the NSP system ID in SAPMMC or not.  (When I start the NSP server, it's all green, except for two red lightning bolts, under
Current Status\R3Services\Background\Utilization 5%
Current Status\R3Services\Background\Aborted_Jobs Job SAP_RSICFDLT (count 18310201) aborted
I have not yet downloaded SAPGUI 6.40, so I'm not really out of business.  I would like to know, however, what's causing the license install problem.  I saw some other posts that are similar, but not exactly, to this problem, so I thought I'd go to the community for some guidance.
Thanks!

Answer 1

My temporary license on NSP WAS 6.40 is expired and I requested a new one. System runs and I can call the logon screen via sapgui but logon to the system is not possible because of the expired license and via CMD (dos box) I receive the following error:
SAPLICENSE (Release 700) ERROR ***
    ERROR:   Connect to database failed
    DETAILS: DbSlConnect failed with return code 99
SQL-ERROR -10709 (check DB manual for explanation)
My WAS 6.20 BSP on another partition runs very well and there I had never a problem. Also the DATABase Manager of maxdb shows no problems and can connect to NSP.
I found many remarks about this problem but no solution is working.
Also the saplicense -test pf=<profile> runs until the connect to the db:
Protocol saplicense test:
Read sapsytem name
       ok, sapsytem name = NSP
Read message server host
       ok, host = xpsap02
Read message server service port
       ok, service port = sapmsNSP
Connect to message server
       ok, connect done
Read hardware key from message server
       ok, got hardware key
Detach from message server
       ok, detached
Check hardware key
       ok, hardware key = XYZA.......
Connect to database
SAPLICENSE (Release 700) ERROR ***
    ERROR:   Connect to database failed
    DETAILS: DbSlConnect failed with return code 99
SQL-ERROR -10709 (check DB manual for explanation)
May be that someone had the same problems and has a quick solution.
Installation of NSP is on drive D (sapdb\programs and usr\sap.. The database is on drive F:\sapdb\NSP
Last remark: The system worked fine after installation on (23/1/2006) until I had to enter the first license.
