Last update, now game won't run?

Is anybody but me unable to run the GW client since the most recent update?

I never had any problems running it before this, but now it causes an error when I try to open it.

I may just need to reinstall it, but I wanted to make sure the problem wasn't the update itself before I took the time.

Thanks!

Run the client with the "-image" command line argument to ensure you have all the content. If that doesn't work, run it with "-repair". This will attempt to repair the .dat file, it might take some time, but should be quicker than reinstalling/downloading everything again.

Thanks, I'll try that!

Edit to update:

I tried both of those suggestions, but each time it returned the same error whenever I tried to access the client.

GW2 still runs normally so I'm pretty sure the issue is the GW1 client, not network settings.

Anything that can be done about that, or just reinstall?

Edit 2: Okay, I feel dumb. I realized I hadn't ever tried just restarting my computer. It worked. All is well.

Thanks again for the help!
