Go look at the OSR documentation:
The FromModifiedDate
filter is very clearly wrapped inside another XML node:
<ModifiedDateRangeFilter> <!-- optional -->
<FromModifiedDate >DATETIMETYPE</FromModifiedDate> <!-- optional -->
<ToModifiedDate >DATETIMETYPE</ToModifiedDate> <!-- optional -->
</ModifiedDateRangeFilter>
Fix your XML so that it conforms to what the OSR shows.
If you'd taken the time to search, you'd find that there is an XML Validator
tool included with the SDK which will tell you exactly what the error in your XML is.
