Hello All! I need advice... I have a Mac desk top and Mac Pro laptop, both operating on Mac OS X 10.6.8 After loading the NXT Software v2.1 on both computers, the program is NOT opening up. It reads: Error code 1003/A required file is broken Has anyone had a similar issue? Is it because the software is not compatible with Mac OS X 10.6.8? Any suggestions in fixing this issue? Thanks a bunch!
