Collatz Conjecture help please

[Gandalf]

I tried to do some GPU crunching at Collatz Conjecture, but their GPU WUs erred as soon as they were downloaded. I have AMD Radeon HD 7700 GPUs with the latest driver.
I tried to post this question on their message board, but you need to crunch points before they will allow you to post which is a little dumb. How do I crunch, if I can't post, because I can't crunch?

So, I have to fall back and hope someone here has my answer. What I'm doing wrong? Is there some additional GPU software I need to do Collatz Conjecture GPU crunching or are my GPUs just not expensive enough for Collatz Conjecture WUs?

Thanks

What is the error messaging look like?
You may not be able to run your GPU as high on Collatz as you were WCG.HCC
Also sounds like there is an issue syncing CPU and GPU portions of the app results, and there is a suggestion that the latest version of BOINC is doing better syncing these pieces.

When the error occur, I adjusted the app_config file to 1.0C + 1.0ATI and it still erred right off the mark. I'll have to make another attempt at running the program, since I Removed it from the Manager because it wouldn't run. I'll have to get back to you about what the error looked like...

Here is the error from the Event log. There was not app_config.xml file...

I've unchecked the solo_collatz project. That should stop the errors.
