Windows 8 store package fails on WACK when login to developer account

I'm trying to put a simple app on windows store. I made a fail attempt once, I submitted an app which failed to pass WACK, eventually it failed on submission too. Even then, when I try to package an app with my developer account logged in, I get a performance launch error.

Even on a blank app. also right after I create package logged in, my app's package name and provider fields on appmanifest are changes too. app's package name changes to the first app I submitted, and the provider changes to I guess my developer account's key.

I deleted my failed submission on dashboard, deleted all the names I reserved, including the failed one. But even when I reserve a new name and package my app with that name, my package name still changes to the very first one and fails on wack.

BUT, when I create package of my app WITHOUT logging in, I mean without associate with windows store, I can package my app with the name I want and pass the WACK. I hope anyone can help me with this.

Edit: C# application.

I had this happen too, it seems like WACK got confused and kept trying to verify the wrong version. The following steps resolved it for me:

1. Uninstall the app from your development PC (as in, go to start page, right click on the app and select uninstall).
2. Reboot the dev PC.
3. Select "Local Machine" and "Release".
4. Start debugging wait for it to have started up completely and then stop debugging.

Pretty sure that only one or two of those steps are actually needed, but not sure which ones.
