older version of PT on top of PT10

[youbringmesuffering]

Ok, i'm expecting a lot of flame spray for this one.

I was running PT 10.3.4 on a macpro, 8-core running OSX ML 10.8.2 through an 003r. Here's the stupid part: i tried to install PTLE 7.4 on the machine. Why? To have multiple instances for rolling back to an older version. Soooo....

now i cannot talk with my 003 via PT10 or the core audio manager. This did work and has been for the last few months.

Things I see:
-Getting "unsupported hardware" in Coreaudio with no connectivity.
-003 is showing up in the system report under firewire AND in Audio Device preferences with 18 channels so the MAC at least acknowledges its meager existence.
-PT does not see it, even in playback engine or Hardware, there is only the Aggregate option.

Things i've done:
-clean uninstall of both versions. now i have just 10.3.4
-reinstall 003 drivers
- Tried force update firmware (aux in->7/8 and Mute trick). PT did not give me an option to update firmware.
-Holding "N" while launching PT10. 003r does not show up
-switch FW ports on the 003r. different cable.

I'm not sure what exactly i did wrong, i mean besides the obvious. but did i roll back to an older version of the firmware, is there something that got corrupted or got crossgraded that doesn't get uninstalled?

I am open to ridicule and harsh criticism as i am a network tech and I should know better so please, feel free. but any assistance on the way would make my day a little shinier.

7.4 is way out of date for 10.8
Try running both the 7.4 and 10.3 un-installers
Re-instal 10.3.4
if you need 7.4 you need another boot drive (you coud split your current OS drive if it is large enough) with an older OS that supports 7.4, 10.4/10.5 or maybe 10.6
