STM8AL3LE88 debug connection error

I trying to debug STM8AL3LE88. There is no problem with STVP in reading and writing device memory and option bytes. But in STVD when i Start Debug it ends with error warning:

Starting debug session...

 -> Emulator reset (usb://usb)...

 ** Connection error (usb://usb): gdi-error [40204]: unknown value for this option

(I've succefuly program and debug STM8S208, S103, S105 etc.)

Can anyone know whats wrong ?

Thanks
