Without code and such it's a bit hard to answer that.

Not sure for CCS, but it might just be because you have the demo version. Still, 16F627 is an old one, 16f627A is the "new" version, much recommended.

I'm much a fan of Hi-Tech C rather than CCS... not impressed at all with CCS... probably one of the many reason why Microchip Bought Hi-Tech company instead of CCS

Anyways, here it's Melabs PicBasic forum, questions about Mplab third-party tool would be better answered on Microchip forum (http://www.microchip.com/forums/Default.aspx?) or via their tech support (http://support.microchip.com/scripts...=webticketcust) or still via the respective third-party forums.
