Repairing Data Archive?

When I log into Guild Wars I get a screen that says repairing data archive and after about 4 mins it finally starts. Anyone know what this is about or how to fix it?

I had a crash but don't know if it's related.

I'm sure I'll have to reinstall the game or something.

Thanks for any help.

I haven't heard about this one .

Reinstalling stuff always works. Do it now .

I've had this alot, showed up today actually. Don't know of any problems from it though.

I believe this happened to me before. I have a couple of screenshots that I'll post.

What I did was go to My Computer > C: Drive > Progam Files > Guild Wars.
Then I deleted the "Gw.dat" file. which contains all of the updates. After I re-downloaded all of the updates, I had this problem no more.

If this isn't what you're talking about, I'm sorry I couldn't help.
