HELP, memory is way low and cant uninstall

[goon55]

Hey all, need some help. For some reason I am not able to uninstall some apps. I get a message saying it cannot be uninstalled but would I like it to still be removed from the app list. Example, I have PocketCM 2.0 and 2.1 both installed and listed on my apps list, but I cannot uninstall the 2.0 version. (or the new one for that matter cause I tried that as well)

My memory sits at:

MAIN

Storage
total 166.41
used 73.66
free 94.74

program
total 46.00
used 41.14
free 4.86

I need to remove some apps, but cannot. Also, is there some special trick to remove apps installed on the storage card rather than main memory? And do the apps installed on the storage card effect in any way the program storage on the main memory?

I am runnign DCD 2.3.2, does anyone recommend moving up to a new ROM thats stable and clean?

Thanks!

Thanks guys.
