I'm build the Box12 project no error. But when I add a new class, I can not build.
And I get the error:

"Error : Cannot find file : C:\Symbian\9.2\S60_3rd_FP1\Epoc32\release\GCCE\UDEB\Box12.exe".
"file I/O fault."
"makesis.exe returned with exit value = 1"

Can anybody help me please??

I'm build project "Box12" for configuration "Phone Debug (GCCE) [S60_3rd_FP1]"
The content of the console error is:
