Alder 32 validation failed

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!!!!

More information is needed, but this is typically the case where the downloaded update got corrupted. Clear your cache, make sure the company that uploaded the updates actually uploaded all parts of the updates (including the *.wys file), and then try again.

Is there anyway I can do this on my own because this was a file that was given to me from a friend, and now I can't use this file because it won't update, it says something is wrong with the client file. Not sure what this means but wondering if/ how I can fix this on my own.

No, this is a problem the person who bought wyBuild should solve. It's not something you can solve.
