[CORRECTED] Strange problem with Xilinx ISE 8.1 and Chipscope Pro 8.1

Hi,

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:

COMMAND: open_parallel_cable PROXYTYPE=xilinx_parallel4 FREQUENCY=5000000 PORT=LPT1 MODULENAME=libCse_CommProxyPlugin TYPE=xilinx_plugin INFO: Started ChipScope host (localhost:50001) INFO: Opened socket connection: localhost 50001 localhost/127.0.0.1 ERROR: This product is not registered. ChipScope Pro can be purchased online at

ERROR: Failed to open Xilinx Parallel Cable

No other changes have been made to the hardware or software.

Any help will be greatly appreciated.

Regards
