Cannot get into admin after installation via magento connect manager

Q: I installed the new version through the magento connect, and it installed fine but then i was locked out of the admin panel with an error. I could only get back in when I uninstalled. Can you help me get this new package installed?

A: Most probably, you have compilation enabled in your magento, please disable compilation before installation and enable cache in magento. Once extension is installed, you can revert all back
