Cannot connect to a Discovery card with ST-link/V1

I have a discovery card F100RBT which is working. I see my old SW blinking LEDs. But now I cannot connect to it. It has been difficult before but now it seems impossible. I have tried with Keil IDE and ST-LINK. Reset active and not. All modes I could change. Nothing seems to work.

I would like use that board because all CPU pins are connected to pin headers, making the board easy to use.

Ok, and do the ST-LINK Utilities work with this board, and are you using the most current firmware, drivers, etc?

In Keil you'd need to use the ''ST-Link (Deprecated Version)'' selection in the debugger to use a V1 device. There were two ST-Link debugger options in uV4.71, the old one might have been removed in newer releases.
