Update caused PDOException error: Implicit conversion from data type nvarchar(max) to varbinary(max) is not allowed.

My setup: Drupal 7.21 / PHP 5.3 / IIS 7.5 / SQL Server 2008

My issue: I just updated this module and ran the update script, and received an error.

This is what I saw on the list of pending updates:

ctools module

    6008 - ctools_object_cache needs to be defined as a blob.

And this is the error that I received after it was run:

ctools module
Update #6008

    Failed: PDOException: SQLSTATE[42000]: [Microsoft][SQL Server Native Client 11.0][SQL Server]Implicit conversion from data type nvarchar(max) to varbinary(max) is not allowed. Use the CONVERT function to run this query.: UPDATE [{ctools_object_cache}] SET [data] = [data_old]; Array ( ) in db_change_field() (line 2988 of E:\mysite\drupal\includes\database\database.inc).

That same error is what appears in the "Recent log messages". I then went into the ctools_object_cache table to see the two columns referenced. These are the properties that I see:

Column Name = data_old
Data Type = nvarchar(MAX)
Allow Nulls = Yes

Column Name = data
Data Type = varbinary(MAX)
Allow Nulls = Yes

The table itself is empty of any data. Is there anything that I need to do to finish this update, even manually?
