Just updated my XFRX from 12.6 to 12.8

When I start to compile, I get the following:

Compiling c:\xFrx_12_8\xfrx.prg
lcText = STRCONV(STRCONV(lcText,6,m.styles.fontcharset,2),2)
Error in line 16053: Too many arguments.

I'm using VFP 8, I'm wondering if he is using a new feature that is only in VFP9?

Thanks
