I downloaded the one on CNET, but it won't do you any good. Since two of my files have different hashes, it could be another reference is used to compare the files. Since the iassdo.dll.mui file might be related to some type of Network security, there may be a key checked to confirm the file. All I can suggest is a completely clean install to test. If you did it on a new or old drive, it would not interfere with your current install. But if you do a reinstall or recovery and you still have the same problem, the file or what might be causing the problem is in that system somehow.
