Cognition 4.5.3 on Samsung i897 (Captivate) - General Questions and Answers

I was trying to install Cognition 4.5.3 on my Samsung GalaxyS Captivate i897. I followed the instructions up to the point of installing ClockworkMod Rom Manager.
I re-flashed back to Android 2.1 (Elcair), and ClockworkMod Rom Manager is not in the marketplace. I did the Samsung Kies Update to 2.2, and then all of a sudden ClockworkMod Rom Manager is available.
Well, I had to re-root the phone with SuperOneClick, and then installed the ClockworkMod Rom Manager, and continued to follow the instructions.
I told ClockworkMod Rom Manager that I had a Samsung GalaxyS Captivate, and then to Install Rom from SD Card. When it rebooted, I went to "reinstall packages" and it crashes with
E:failed to verify whole-file signature
e:signature verification failed
Installation aborted.
Any ideas?

[Q] Galaxy S2 GTI9100 JPKG2 CWM

Hello All,
I am new to the world of rooting and flashing but seriously wanted to have a new ROM for my Galaxy S2 GTI9100 bought in Dubai. It is running on GINGERBREAD.JPKG2. I had rooted this somehow (not through ODIN) and has super user access now. Have installed the ROM Manager but could not get the CWM to work. When I Reboot into Recovery", It says "E Signature failed" and aborted. I also have copied Resurrection remix ROM into the SD memory but cannot flash it to update the OS as it says the same error. Can somebody guide me what exactly is happening?
