DayOfMonthException

[tstrobel]

Hi there,

since this week, my projectserver 2007 is throwing a
DayOfMonthException, when I load the page "mywork.aspx" to see the
tasks assigned to me by.

The complete error is:

Type 'Microsoft.Office.Project.Scheduling.DayOfMonthException' in
Assembly 'Microsoft.Office.Project.WebProj, Version=12.0.0.0,
Culture=neutral, PublicKeyToken=71e9bce111e9429c' is not marked as
serializable.

Any idea how to solve this problem?

Best regards,
Strobel
