When I try to upgrade from beta 5 to beta 6 it hangs on 

Preparing your update...

 

Any suggestions? Is there a way to get this any other way?

 

You can also download the beta in your client area.

Yes, however this will be a full blown "from-scratch" installation. I would like to somehow get the customized one that the control panel produces.

Bumping for an update - Is it possible for me to source this update to 8? Still cannot use the ACP to do so. I would prefer not to have to start over.

Why not download it from the client area, then ftp all the files up to server replacing the beta 5 files with all the beta 8 files and then run the updater retaining the config.php file from beta 5.

I would like to be able to keep all the custom themes and such

Any reason why you're not upgrading to RC2?

​I'll tell you that some of the themes made in B5 have issues. I have to rebuild all of my early themes.

​Anything prior to IPS 4.0 as in skin themes, applications, mods and such are of no use nor will work with IPS 4.0

***ADDED***

Mis read that you already are using IPS 4.0....

Beta 8 might work... RC-2 is out now but there are a ton of css changes that were made in the RC versions so you will have issues with your custom skins until these changes are fixed...
