The daily job has been running for years now. Yesterday, it failed due to corrupt .prt.xml file that belongs to an old partition from 2012:
OnError,PC,NT AUTHORITY\SYSTEM,Update Dim 1,{865AA3E5-2D32-4DF0-86EA-0B76DDE42C43},{AA4713D8-B06D-4287-836B-4DCC54B5CDF9},3/13/2014 9:56:13 AM,3/13/2014 9:56:13 AM,-1055981562,0x,XML parsing failed at line 1, column 4: Unrecognized input signature.

object from the file, '\\?\E:\sqldata\OLAP\Data\OLAP.0.db\Statistics.0.cub\Statistics.2233.det\Statistics Week_15_2012.691.prt.xml'.
To fix this I tried copying the xml from week 14 and updated accordingly (eventually I couldn't update object ID) then restarted SQL Server and as a result, the XML was deleted along with the corresponding partition folder.
Today, the job did not start automatically and when I kicked it manual using Management Studio, it failed again with the following error:
OnError,PC,NEGOLAPPC\rkheir,IncrementalOLAPUpdatePackage,{F423D795-224C-4060-91D4-39677031038B},{E8F46E27-4F46-4A9E-8886-390AD7D94BCA},3/14/2014 2:51:31 PM,3/14/2014 2:51:31 PM,-1055981562,0x,XML parsing failed at line 1, column 1: Incorrect document syntax.

When I open the XMLs in the error logs they look like binary contents (unreadable). Other XMLs are readable...
Any idea what may be causing this?
NOTE: The partitions with the corrupt XMLs are old ones that are not being processed anymore... currently the partition for statistics is week_12_2014... We're using SQL Server 2005, will be updating to 2008R2 soon but need to resolve this issue first.
