This somewhat depends on where you put the if-else statements and if you had them all properly scoped. If you're putting these in an interrupt service routine, then it might just be taking up too much time and you'd get a red light of death. If you're doing this elsewhere then timing shouldn't be an issue. You might instead have some misplaced braces that are causing you to skip past the PutData() command or something. C18 doesn't seem to do anything too stupid when compiling nested if-elses, so I'm unsure what else this might be unless your code is so long that it needs to be using the large code model and you're not using it at the moment. Perhaps if you just tried re-compiling your original code. I can't think of anything other than a corrupted file that would keep the controller in a program state after a download.
