Launcher or game wont start - DBC over 1.3GB

[vincenzo0506]

So, I have been all over the forum.   I see plenty of references that say don't delete the files in DCCACHE.

I think mine is amess.  Shortly afer the update in June, My system stopped working.  Doesn't matter if I run the launcher or the game.   I see it in the task manager.  It sits and consumes memory.  Up to 1.4 GB and then it dissapears.

Naturally there is nothing in the Windows event log.

From what I read, the problem is my DBC files.

dcdb0.dbc is over 1.3GB.  There is a dcdb0.dbc.diabaled file that is 205mb.  my matching EBC file is 104mb.

What are these files? 
Why are they so big?
What do I need to do to solve this problem?

IF this has been answered somewhere and I missed it, I sincerly apoligize and would appreciate a link to the solution.

Thank you all,

V.

You are right.  That is an enormous size for a DBC.

You can delete your DCCache but you will lose everything you have installed through your Launcher.  In your case, that might be a good thing.  You must have something rather nasty going on there. You should also delete your DCBackup and the four caches.
