Again... thank you so much for all of your help! I did not have 64 bit verion installed. Now that I do, I get the error 5: You have files in the configuration file that are normally compressed, but then failed to remove/rename X.uncompressed_size file. Normally, this isn't fatal, except that there were no files left to check, so the program had nothing to do. I have all the steps down, so I am unsure as to why there is no files left to check. Maybe I am doing something wrong with the XComGame.upk step... I put the Decompressor in the CookePCConsole with in, run command and type in the command to decompress. I take the file named XComGame.upk from the unpacked folder and drag it into CookedPCConsole folder and overwrite the old one. Then run XSHAPE.bat UPDATE: OK, I was not deleting the uncompressed file... oops. deleted that and then got error 16 - edited bat as instructed, but game will not start. I did get a message that it was updated UPDATE 2: IT"S WORKING!!! thanks so much for all of your patience guys!!! To recap, my problems were: * Needed 64 bit version of java installed * Had to delete XComGame.upk.uncompressed_size (may sound strange, but this did not seem all that obvious... it sounded like I was to rename the XComGame.upk to this... I finally noticed a file already named this) * Had to edit XSHAPE.bat to hav a 0 after -V * Game ran when opened through steam, but not by manually opening through .exe I hope this helps any of those non expert users out there like me :-)
