If your MSE = 0 (which is highly unusual) it would indicate no within-subject variation....e.g, making up a two group example with n = 3 for each group).........
Grp DV
1 2
1 2
1 2
2 4
2 4
2 4
so first of all, is that the structure of your data?..if so, you need to see if it is a data entry error as to why a constant (or close to boundary condition) has been entered within each group.........or is it some structure of the design?

Hi all,
I'm doing a two-way anova in SPSS (using the General Linear Model option).
Accoring to my output MSE=0, thus no F-values get calculated. Any idea why
this is happening? Can this be due to small sample sizes?
