I simply do not understand what is so difficult about finding the instructions for installing Awesomemod.  It's labeled "How to Install the Framework and Awesomemod!"  It is amazing how many people refuse to read instructions and want someone to give them the information personally.  Please, you cannot use a computer without learning how to read; avail yourselves of remedial reading classes first and then return to the computer.  I am so tired of looking for information and having to sort through the whining to find it.  Like anyone with half a brain, I know that I must revisit the instructions if something I have done doesn't work.  Inevitably, in my haste, I have skipped a step.  Imagine, when I follow all of the steps, it works!  It's like magic!

I have been receiving error code 13, almost from the beginning (about 2 weeks after I began playing).  I have had them with and without CC; with and without Awesomemod; playing for long periods of time, or short.  I've tried all the "voodoo" fixes and some worked...for a while.  I added memory, which seemed to help...for a while.  I don't remember when I began to get error code 12, but it seems just as random.  I had someone look at it and he surmised that it looks like a video leak.  There was a place in the logs in which, he said, it seemed like the game was trying to use the video card memory instead of system memory.  He also pointed out that, if this is indeed the problem, there would likely not be a fix for it because too much would have to be recoded.  The best I am able to do is to save about once an hour and shut the game and restart after two hours. Unfortunately, I sometimes get involved in the game and don't save or shut down in time, which brings on the inevitable error code (either 12 or 13). Saving more often than once an hour doesn't seem to help, and sometimes I get the error if I save too often!
I can only share what I've been told, as I just play.  I love mods and appreciate the people who create them, but have no such talents myself.
