did you get yourself sorted out? what you have just experienced is the main reason i personally avoid rom manager. it does not always install tings correctly,and it is an APP in a working rom,and as such will not always be available for you to use. i would pretty strongly reccomend that you avoid rom manager,and use the menus in recovery to manually flash,wipe,backup,etc. to fix your boot loop,go to clockwork recovery, -wipe data/factoiry reset -wipe cache -wipe dalvik cache now you can either: 1)restore a working backup or 2)flash a rom if you wish to flash cynaogen again,i would download cyanogen to your PC. download and install an md5 sum checker to your PC so you can compare the md5 of your download to the one the cm lists for what you downloaded. once you have verified the md5,transfer the download to your sd card so you can flash it in recovery. make sure you have transfered the reccomended gapps to your sd card as well,and flash it immediately after flashing the rom.
