I have this:

In the shortcut: C:\Users\invencible895\Desktop\cgminer-3.8.0-windows\cgminer.exe --scrypt -o 127.0.0.1:18199 -u test -p bitcointalk
And the cgminer closed automatically, i did many attempts without shortcut and have a crash.

you don't need to launch the bosscoin client in prompt mode, just launch it normally w8 for sync, and then start cgminer, this for solo mining
