Chipscope inserter changes net names.

Hi All, When I probe nets with Chipscope Inserter, the net names change. For example, 'clock_enable' changes to 'ila0_trig0'. This screws up my timing constraints declared in my .UCF file. E.g. NET "clock_enable" TNM=FFS "ff_grp1"; doesn't see the net anymore. Anyone solved this? Cheers, Syms. p.s. I'm using version 6.2.02 of the Chipscope software. I'm downloading
