MSSQL2005 Analysis Service Distinct Count

Question

hi,
i am currently trying to build a distinct count on my cube (mssql2005 analysis services).
But after i added the discount count on the field i want to and start the processing, the following errors appear.
- Errors in the OLAP storage engine: The sort order specified for distinct count records is incorrect.
- Errors in the OLAP storage engine: An error occurred while processing the 'FACT VIEW STATISTIC' partition of the 'FACT VIEW  STATISTIC 1' measure group for the 'Accident Statistic' cube from the OLAP_PROJECT database.
the count measure works fine.
will appreciate any help on this distinct count problem.
thanks in advance.

I also received this error:
"Errors in the OLAP storage engine: The sort order specified for distinct count records is incorrect. "
Running SQL Server 2005 SP2 Enterprise Edition
The collation between SQL Server and Analysis Services was the same.
The distinct count was on a character data type.
There were no NULLs in the data.
The cube was processing fine until new data was added.
After some investigation into the data it seems that the culprit was one row that the data length was 13 characters on the column of the distinct count. Everything else was less than 13 characters. (See results below). Updating this one row solved the problem. The exact value of the data is: '1-4296-175-9'
Here is a result set:
select len(columnname) as data_length, count(*) as count
from [tablename]
group by len(columnname)
order by data_length
data_length   count
2    3
5    1
6    3
7    2
9    1
10    856
13    1
My question though is if SQL2005 can do distinct counts on strings then why choke on one row with an extra length?
