[Q] Rebooting into recovery problem

I posted this in the Noob thread but got no help there for 13 hours now and Im kinda in a hurry so here's what it is; Okay, so whenever I reboot to recovery and press re-install packages it tells me it failed to do so for some reason after two seconds and the font stays purple. Any suggestions guys? Should I proceed to install the ROM using Rom manager? Is this normal? Please answer I have to finish this today, I've no other time.

Are you already rooted and trying to flash a rom? Not enough detail here to work with

Yes I am. And if its the update.zip file that is corrupt then kindly link me to a valid one.
Use rom manager and get a new one

[Q] HELP !

So I've recently tried to ROOT my Vibrant with Cyanogenmod 10 to install Jellybean on it. This phone has never been rooted before or anything. I was told I had to root it before hand aswell. When I Go and do the root on my Macbook. I used Oneclickrootmac. It's asking me to intall a update from the memory card to the phone. When I do so, all I get, aswell as when I try to install CM 10 on it, Is an error on it saying Signature Verification Failed, and the installation has been aborted. Can someone please help me with this problem I'm currently having ?

This question is nothing new, Its not as if you're the only person to ever want to install cwm. Rule #1 of xda rules is to use search before creating topics.
Flash Siyah kernel v4. Flashing a custom kernel gives you root, custom recovery (cwm) and superuser.
If you want any more details then that I suggest you have a look at the other topics where this question was asked and answered. Or have a good look though the link above and learn. Rushing into things will just lead to you having problems.
I used this guide for installing CWM, the first point shows you how to. http://wiki.cyanogenmod.org/index.php?title=Install_CM_for_i9100
