Can not Roll up the Duration after upgrading to 2003

[AC]

After I upgraded to MSProject 2003 I cannot roll up the durations of the
tasks at the summary level.

I installed the SPack as well, but to no avail

Any help appreciated.

AC,

What is the exact error message or symptom? By what means are you
"trying" to roll up (which I assume means sum) the durations? By chance
has automatic recalculation become turned off?

Finally, and perhaps this is the root cause of the problem, think about
what it means to add up the durations? You should not expect the sum of
the durations to sum up to summary level. At the summary level, the
duration will be the time duration between the start of the earliest
subordinate task and the finish of the latest subordinate task, less any
non-working time in that interval.
