Hello I am new to the forums, however I have played the game for awhile now. I have followed this thread for the past few days after encountering this error my self and have a solution of my own to add. My brother and I have come up with program that will batch convert all the 24 bit PNG files in the parts folder to 32 bit format using the .Net Framework 4.0, this may also work on Mono for Mac users as well but this has not been tested. You can download the program here: http://dl.dropbox.com/u/10945047/KerbalImageConverter.zip This program has been tested a few times with no issues, however we still recommend that you back up your files to be on the safe side. All you have to do is place the EXE in your KSP folder and run it. Note: It will take a few minutes to convert the files if you have a lot of parts. The source code for the program is be available upon request. If there is any features you want to be added to the program just ask.
