Ok so I got a file from one of my friends and it needed to be updated and it has updated before on my computer but today it said alder 32 validation failed and it won't update so I can't use it and I have no clue how to fix this, can anyone help, and also I have no clue on how to rebuild the files and all that. Is there a easier way to get the update or no??? Also it said something with the client file can't be in the update folder and it was, so it said that it can't operate on my computer or something. SOMEONE PLEASE HELP!!!!! MUCH APPRECIATED!!!!
