Hi @ all guys.
I have installed the new C compiler(3.11b student edition) with your patch but this don't resolve my problem.
Stefano Stella, another undergraduate student that work on Flex says that this problem isn't so important and the program works fine equally.

But now I have another problem, my license has less than 14 days remaining.Why this??I have download the student edition after sign in on Microchip web site.C&i

Thank you for any advice
Daniele

This is normal... the C30 student edition has an evaluation period of 30 days, after that you need to register (I think it's free for students, or witha reduced price). If you do not register, optimizatios are disabled (but ERIKA works also with optimizations disabled...)

Ciao,

Ok Thankx Paolo.
