Backup 3.60 failed with "Compressed BLOB"

Hi! When I try to backup my 3.60 (SQL) Database with the SQL-Fin-Client, after 100% done, the client tells me, that he can’t open a compressed BLOB-file, it’s a unknwon format … WHERE ARE BLOBS IN MY DATABASE? No pics … no embedded something … The SQL-DB is ok, I tested with “DBCC checkDB” - no errors. [V]
