If you're running a custom ROM such as CM, certain display settings (such as a system-wide icon pack, DPI, resolution, etc.) might have been altered. Themer works best on stock settings, therefore resetting these back to default should fix the error.
For after the changes have been made, try this:
1. Uninstall Themer.
2. Delete the /sdcard/MyColorScreen/ folder (removing the Exported folder within it if you saved any themes).
3. Reinstall Themer.
