2014-12-28 21:34:04 [SEVERE] [ForgeModLoader] There is a binary discrepency between the expected input class bcw (bcw) and the actual class. Checksum on disk is 2b1d1a46, in patch 10849a00. Things are probably about to go very wrong. Did you put something into the jar file?
2014-12-28 21:34:04 [SEVERE] [ForgeModLoader] FML is going to ignore this error, note that the patch will not be applied, and there is likely to be a malfunctioning behaviour, including not running at all
2014-12-28 21:34:04 [SEVERE] [ForgeModLoader] The minecraft jar file:/C:/darkearth/DarkEarth/bin/versions/1.6.4.jar!/net/minecraft/client/ClientBrandRetriever.class appears to be corrupt! There has been CRITICAL TAMPERING WITH MINECRAFT, it is highly unlikely minecraft will work! STOP NOW, get a clean copy and try again!
2014-12-28 21:34:04 [SEVERE] [ForgeModLoader] FML has been ordered to ignore the invalid or missing minecraft certificate. This is very likely to cause a problem!
2014-12-28 21:34:04 [SEVERE] [ForgeModLoader] Technical information: ClientBrandRetriever was at jar:file:/C:/darkearth/DarkEarth/bin/versions/1.6.4.jar!/net/minecraft/client/ClientBrandRetriever.class, there were 0 certificates for it
2014-12-28 21:34:04 [SEVERE] [ForgeModLoader] FML appears to be missing any signature data. This is not a good thing
