Droid 2 App Installation Errors

[TheFuhrerinator]

Hi, this is my first post on this forum, I've been all over the internet looking for solutions but couldn't find any. I've had my Droid 2 since November of last year (2010) and have been having some issues trying to install certain apps. I've been using the Amazon App Store a lot, and been downloading the free app of the day almost every day, but some of the apps will not install. They will download completely, but once I go to install it, it says "application could not be installed". Sometimes it won't even let me go to the installation page and gives me an error message that says "app has a package error and cannot be installed".

If anyone has a solution for this problem it would be awesome! I've been looking everywhere for a solution and cannot find one! Thanks in advance!
