Windows 7: APPCRASH w/ Exception code: 0xc0000005

I've been working on this for a week now... HELP!!

Setup:
Windows 7 Ultimate 64bit
HP Pavilion dv7 Laptop - Intel i5/8GB RAM/ 1 GB ATI Mobility Radeon HD 5650 dedicated video card
Chauvet X-Factor DMX interface (USB powered) - seperate USB bus
M-Audio Fast Track Ultra USB audio Interface - seperate USB bus
ShowXpress 6.25 (including current windows Fix)
Cakwalk Sonar Professional 8.5.3

Usage:
Using Cakewalk Sonar files to control ShowXpress via MIDI linked with LoopBe1 virtual MIDI driver. I've used this combination for our shows for the past year on an older Compaq running XP with no problems whatsoever (Running Sonar 6 and ShowXpress 5-something). That computer is done with so I've upgraded.

Problem:
While playing through song files in Sonar, thus triggering MIDI to ShowXpress, I get ControlBoard.exe APPCRASH errors. Sometimes I can go 1/2 hour. Sometimes not even one song.



Here's the complete error - - - - - - - - -

Faulting application name: ControlBoard.exe, version: 0.0.0.0, time stamp: 0x4cacade1

Exception code is always the same: 0xc0000005

Through msconfig, I've disabled AVG Antivirus, as well as many other services and programs.
In device manager, I've disabled the wireless networking device as well as the internal audio devices (analog mic/speakers & HDMI audio device)

I've disabled Windows firewall and disabled DEP for ControlBoard, Live and ScreenControl...

Nothing has stopped the problem... I'm am at a loss... A beast of a laptop and I'm stuck...

Am I missing something??

TIA

I've also ran the latest mem86 3 times from the ISO provided on their website - no memory problems

I'm not well familiar with either Cakewalk Sonar or ShowXpress, but they may just not work well with
each other. If your ShowXpress is not the latest try reinstalling it.

Control Panel -> Programs and Components -> uninstall ShowXpress. Then use Revo Uninstaller or CCcleaner to clear your system of ShowXpress remnants.

FIXED!!!

Well, turns out it was an issue with Sonar sending too much MIDI infirmation to ShowXpress... It was sending MIDI Time Code at 30 frames per second plus whatever actual MIDI data that was programmed. I don't need the MTC to be transmitted, so turning it off fixed it. Thankfully it wasn't OS or driver related.

Consider this issue closed.

Thanks!
