Where did you e-mail them? How is this done?
I have the latest update of Lion, and now, I can not open Mainstage in 64bit mode. The "Concert" stays open for a moment, then crashes. It will stay open in 32bit mode, but I need it in 64bit mode. I'm not exactly sure how to revert back to 10.7.3, but I do have a back-up in late March, so, there's probably a way.

Are you able to share this "fix"? I have had no response from Apple

Contact this address below and request a new download, and that the one you have does not open or it crash whe doing so.
They open up my account and allowed me to reinstall.
My redowndloaded Mainstage is now working on my MacB Pro, and four  externals, with out any problems.
Hope this will help others, who are having a problem with Mainstage v 2.2.1

I already wrote the fix in this thread:
I got a hint from a friend, that seems to fix this problem:
- Control-Click into the toolbar of MainStage, select "Customize" and remove the CPU/MIDI/Memory meter display.
If you want to add some additional safety: switch MainStage to 64-bit mode.

Blueberry's hint seemed to work for me. Apple should really properly address this issue though. Thanks!

Blueberry's hint worked for me in the last rehearsal. Mainstage did not crash. hopefully it will run the same on stage as in the rehearsal studio.

Timraaf, did you do Blueberry's hint?
I am sticking with 10.7.3 since I read many posts with this problem...

No pearls of wisdom from me but I thought I would add my name to the list of users with a problem following the update. iMac running 10.7.4 crashes, Mbp on 10.7.3 is more stable but still getting random pu spikes which I can't track the source :( c'mon Apple, sort it please!!

Just confirming that removing "CPU/MIDI/Memory meter display" on the edit page fixes the crashes and all the problems that came with 10.7.4.
Thank you Blueberry.

Additional confirmation that removing "CPU/MIDI/Memory meter display" fixes crashes:
I ran Mainstage for 36 hours solid but dipped in and out of Sibelius, Safari and Netflix (something any sane person wouldn't do during a gig!) - no problems with Mainstage, even waking from sleep OK.
Hope that helps!
(and thanks Blueberry for the tip)

Played a casino last night. Had to restart MS 4 times before giving up and running keys direct.
Backing up on time machine, then gonna try a couple things.
Before 10.7.4 all was good. I hate going backwards, so we'll see.
This thread is much appreciated!

I think it is something that has definitely occurred after the latest update, and I hope it's fixed soon. Somehow, starting up is a problem. I have found that if I can open a "new" project, and from there open up any file I normally use, I have no problems. If I open the file directly it will crash every time.

Wouldn't it be nice to have some official advice or instructions from Apple instead of relying on hints and forum banter? I would like to install OSX 10.7.4, but won't because I rely on MainStage for live performances. Has there been any word from Apple on this?

I am getting this problem as well now. Has anyone figured out a trick to avoid it yet since last post?? I am running Mainstage 2.1.3 32-bit on a Mac Pro 2.26GHz Core 2 Duo, 8Gb ram. It mainly happens with Soft Instruments that are sampled in things like the ESX24.
