ULINK2

I have just connected a ULINK2 to my development board and i get communications error.

The device is a ADuC7026 (ARM7TDMI core)... A few Questions??

The uVision3 options for the debugger gives 2. ARM Debugger & ARM7 Debugger Which Should I use??

If I select the ARM7 one i get an error message, "Missing jarm.dll"
If I selet the ARM it gets further but there is JTAG Communication Failure against the TDO line

Second question...should the TDO line on the chip goto the TDO on the ULINK or should there be crossover with TDI->TDO and TDO->TDI
