Random23 Posted October 12, 2006 Report Posted October 12, 2006 Sorry to say that without the original source file you are stuck. This file has a line that reads KNOW_HOW_PROTECT in it under the header of each block. You need to remove this from the source file to get to that block. Quote
Groo Posted October 13, 2006 Report Posted October 13, 2006 The 'scroll down' message meant to scroll down the message board as others has asked the same. There is a way to remove KHP without the original source, most people do not like others infringing copyrights etc though. Quote
