Why are my database files (.dbf) updated but not the cubes (.mdc) ?

Answer: The cubes are not run/downloaded properly.

(assuming you have scripts to run the cubes)
Double check if the date of the cubes is as at current.
Else do the following :
To click and run the script again - manually
How to run manual:
1. Cognos Powerplay Transformer
2. Open "...... .pyi" (Usually the name is the same as the one in .mdc, just that you have to open the corresponding .pyi file)
3. Click on the cube icon to run the cube.
OR 
If you have scheduled a task to run the script automatically (which will run the cubes), then you might also wish to wait for the next update (depending on your scheduler: Control Panel > Scheduled Tasks) and then check if the cubes are now updated.

Problem logging into windows XP (no password-safemode, blue screen persist)

1)
Try to log into the safe mode and do what was explained/advised in :
http://answers.yahoo.com/question/index?qid=20070409184255AAuAqLp

However, there is no open box for me to type in the passwords in the windows xp blue welcome screen in safe mode.

So i tried ctrl-alt-del and then a dialog box appears with username and password.
Username : administrator
password : control userpasswords2

But the above password doe snot work.
 
 2)
Tried administrator / (password leave blank) , administrator/administrator, etc all kinds of generic combination, but still doesn't log on.

It still goes back to safe mode with 2 avastar showing - 1 for administrator and 1 for user, without any open white box to type in your password. and when clicked on the administrator avastar, it shows "loading personal settings" ...."saving your settings" and then back to original position. --- (a)

And then, if clicked on the user avastar, it will show "logging off....loading personal settings...saving your settings.." and then back to the original position. ---(b)

Previously, prior to logging into safe mode,  scenario (b) happens.
so I tried to copy userinit.exe file from another PC, rename the file to wsaudaptor.exe and then copy this file into the systems32 folder. however, it doesn't solve the problem either.
