The file provided from Cobra 8.1 includes a new item called "Owner=SYSADMIN" embedded at line 794. The meta data associated with the file indicates that it is designed to be compatible with wInsight 6.2 and higher (<wInsightDb version=6,2,0,0">), yet it fails to load in wInsight 6.3. It may load in later versions of wInsight, but we cannot verify that.
To correct the file, modify line 794 from <Contract id="cc1" Owner="SYSADMIN"> to <Contract id="cc1">. The supplied file will import as expected for both wInsight 6.3 and Empower.
Encore Analytics completed an enhancement to Empower in verion 3.5.2.48 (March 4, 2107) that will trap and automatically workaround the data anomaly introduced in the recent version of Cobra.
