Ethernet Display text on led matrix?

i have the code for displaying finished and working, and the code that fetches ethernet also done. When i try to compile my current sketch( ), it says "cannot convert 'String' to 'char*' for argument '1' to 'void printStringWithShift(char*, int)'", i have been google searching for hours but could not find a solution to this. Any help?

No one's going to download a virus or worm or who know's what from pastebin.
