Delete your ijji folder, ( Before you do this, if you have any screenshots/replay tapes you want to save I recommend you do this now )
And then, delete the aeria games folder, and uninstall soldier front + aeria ignite.
Now, for the fixing part, you should be able to redownload aeria ignite, and download soldier front from there. If this doesn't fix your problem, I've got a few more suggestions. Let me know.
