We have been using Xilinx ISE 8.1 (foundation, evaluation license) and Chipscope Pro 8.1 (evaluation license) with an ML 403 board. Both above tools could talk to the board via a PC IV cable without problems.
The trouble started when the evaluation license of Chipscope Pro expired. The original CS Pro install was erased and a reinstall with the new reg. key was done (before erasing, a recursive diff showed that the only difference between the two installs was a single line in the license.dat file).
Since the reinstall, whenever CS Pro is invoked from within ISE, the following error messages are output:
No other changes have been made to the hardware or software.
Any help will be greatly appreciated.
Regards
