Cannot compile; error: expected type-specifier before 'CRemoteXYStream

I'm brand new to RemoteXY, I thought I'd try it out with an ESP8266 relay board and an HC-05.

I've set the board to Generic ESP8266 and added RemoteXY library however if I use SOFTWARESERIAL I get the following error, if I use HARDWARESERIAL it compiles fine.

If I set the board to an Arduino board it doesn't compile and presents the same error, which leads me to think it's something with my environment rather than a systemic issue or bug.  I'm hoping I could get some suggestions here?

Here's my code, the operational parts (relay on/off) aren't complete;
