I've heard that GCB works pretty good & I down loaded several weeks ago and it worked well at that time. My hard drive crashed and I tried to down load it again to continue to work with PICs. I down loaded several times and I keep coming with this problem --> 0xc0000135. Which states that the program did not load properly because that the file was incomplete. Can any body help?
