[Q]Can you flash over a flash

Hi All

Please let me explain in detail:
1. I had original ICS and flashed CF-Root with ODIN
2. Flashed new JB-Polland with ODIN
3. Lost root access and CF apps
4. Re-flashed CF-Root, CF apps and root access granted
5. Opening CWM i get the following msg: "This version of CWM should be used with CF-CWM v1.1" Now from reading other posts, i think this error is due to CF-Root not supporting JB.

Therefore what are my options?
1. Can I flash a new root over CF-Root, that supports JB.
2. Do I do the triangle away and try to clear CF-Root
3. Any other suggestions?

Thanks in advance guys.
