ULINK2 was working - now no communication

Help,
I have a BLE SOC ARM Cortex M0 and a ULINk2 connected to the debugger in SW mode.
EVERYTHING has been working fine until now.
My device is programmed and running. I see the BLE advertisement. It is not asleep.

I now cannot program this device, or any other board of this type with the ULINK2.
I have FW version2.02 and uVision4 V4.73

I programmed the device last night, now I get
SWD COmmunication Failure

The ULINK USB sees the ULINK2 etc.

I have tried using the UL2_Configure utility. I did have it set to ULINK because I needed to work with an older version uVision4 for a different project.

Any clues?
