NOTE: I am aware there have been other topics with the same problem but most seemed to say that it had been resolved and I couldn't find an answer.--
Just download FlashPunk and started following the tutorials @ http://useflashpunk.net/tutorials/ , I tried to Test my project but I got this message saying:
Compiler Configuration Required
This project doesn't have a valid SDK defined. Please check the SDK tab in the Project Properties.
If anyone could give me some nice steps to fixing this problem I would really appreciate it!
