Installed CM9 but now I can't access WebOS - PLEASE HELP

Here is a rundown of what I did to install CM9. Hopefully someone can tell me where I went wrong and/or how to get WebOS back and still keep CM9 -

• Booted into WebOS
• Connected the TP to my Windows 7 PC with the USB cable
• Navigated to TP drive and created folder named cminstall
• Copied 4 files into the cminstall folder (cm-9-20130324-NIGHTLY-tenderloin, moboot_038-tenderloin, update-CWM6_tenderloin-20121215, and update-gapps-ics-20120429-signed)
• Unmounted TP from PC
• Shut down TP
• Rebooted TP and started webos recovery mode
• Reconnected TP to PC using USB cable
• Ran the file "webosdoctorp305hstnhwifi" to add the Palm, Inc folder to my C drive, Program Files folder
• Unzipped AcmeInstaller3 and Uninstaller into the Palm, Inc folder
• Opened a command window on my PC
• Typed cd C:\Program Files\Palm, Inc
• Typed novacom boot mem:// < ACMEInstaller3
• 2 penguins and a bunch of lines of text started to appear

After that, I got the list of options to choose between WebOS, CM9, etc. I chose CM9, proceeded to set up the Wifi, time/date, etc. I was able to log into the Play Store and download and use some apps so I assumed everything was fine. Then I tried to get back into WebOS, but when I choose it from the boot menu, it just sits there on the glowing HP logo and doesn't go any further.

Please help. This isn't even my TouchPad, it's someone else's, so I don't want to screw it up.

 

Probably a dumb question, but how exactly do I run the uninstaller?
