I have a huge problem with code blocks.

Recently, I uninstalled code blocks. I couldn't find the application of Code blocks under "Uninstall a Program" in Control Center, so I just deleted the Code Blocks directory manually. I then downloaded visual c++ express 2010. After a week or so, I decided that I didn't like it, so I uninstalled Visual c++ 2010 and reinstalled Code blocks. After that, I updated the compiler with the one at:

http://nuwen.net/mingw.html

I changed the directory information in Compiler toolchains under GNU GCC with the appropriate ones. But, every so often, a random message appears on my screen:

Cross-platform IDE built around wxWidgets, designed to be extensible and configurable. has stopped working

The program then crashes. This happens randomly and I don't know the cause.


Help needed urgently.

ANOTHER PROBLEM!!:

I am getting an "Environment Error" Can't find compiler executable in your configured search path's for GNU GCC compiler"

This happens whenever I start up code blocks. When I go back to compiler settings to see what happened wrong, the default compiler packaged with CodeBlocks is used instead of the one I just downloaded. I keep resetting the directory back to the new one, but every time I open code blocks, the compiler displays this message and resets the directory back!

ALSO:
Cross-platform IDE built around wxWidgets, designed to be extensible and configurable. has stopped working

only appears when I build my project. It builds and runs successfully, but right after that, it crashes.

I doubt that has anything to do with how you "uninstalled" Code::Blocks earlier or how you configured the new installation. The toolchain is only invoked when you build or debug a program. Code::Blocks is probably just crashing. I'd try building it from source with debug information to see what's causing the crash.

EDIT: You could try deleting the configuration files, which are probably stored in AppData\Roaming\.

How would I do that?

Also, now the compiler isn't even working!
It is giving me an error when I build a program saying that the compiler is invalid.

EDIT:

I tried deleting defauly.conf and an option popped up with all the compilers. All of them were shown as invalid.

I tried deleting default.conf, but now it says the compiler that was packageed with codeblocks cannot be found. What if I reinstall codeblocks and the new compiler, would that work? Should I just installed the version without the compiler and then download the compiler separately?
