Hi All, I am facing problem while using allegro.I have taken one of our old design for revision,amidst working it gives error message "allegro.exe has generated errors and will be closed by windows.You need to restart the Program". I am using V14.2 for this design. Anyone knows how to overcome this. Thanks in advance. Trilok Budathoki GE - India Business Center, *: 91-40-27881731 * : trilok.budathoki@xxxxxx
