This is an issue with Compass 0.12.4.
Follow the issue here: https://github.com/chriseppstein/compass/issues/1618
You need to uninstall compass 0.12.4: gem uninstall compass, and then install the latest working release: gem install compass -v 0.12.3.
I'm not working on windows, but best guess it seems like ruby doesn't have write permission to your target directory E:/CRM_workspace/CRM_from_repo/ria/.tmp/styles/main.css, so check for that. I don't know about permission control under windows, maybe you should give ruby administrator rights or let E: for everyone writable.
UPDATE: As far as I know, this problem is related with sass's version, so try to update your compass to v3.2.18 at least.
You check the current version with command: gem list sass, and update with command: gem update sass, good luck and keep me posted.
