Do your repeated measures factors have only 1 d.f. (2 levels)? If so sphericity is automatically met and some tests or corrections for sphericity will return errors (depending on software). Use the standard sphericity asumed ANOVA output in these cases. If you have no between-subjects factors then it should not surprising that tests of the factors return errors (depending on software). (Another possibility is missing cells in the repeated measures design or empty cells in the between subjects factors).
