So, in the process of clearing out some memory of my SD card, I believe I deleted some of the apps that I moved to the SD card XD. Now, whenever I try to download chompSMS, or StumbleUpon(which were on my SD card) from the market, it says that the package file is invalid. I'm running Velocity 1.1, not OC'd. Halp? TL;DR - I cant install chompSMS or StumbleUpon after deleting the stuff they had on my SD Card. It says, "The Package File is Invalid".
