Haven't used 300SMS in awhile. When I went to launch it today I got a launch error message. I reinstalled the app over the old app and got the same message. When I tried to delete the app I got another error message telling me it couldn't be deleted--probably in ROM. I tried to delete it using Filez and got an error message indicating it couldn't be deleted.

The only hack I have going is McPhling. I disabled that but got the same results.

Any ideas?
