[pluggo] get DP5.12 working after Pluggo-induced crash

any quick workarounds to get DP to launch?  it crashed after fiddling with PluggoBus send/rcv plugs.  crashes every time now, even after dragging out DP prefs.
i know i could reinstall everything or remove Pluggo temporarily, but i wondered if anyone knew of a quick fix, like a Pluggo prefs file or somesuch.
i'm a pretty experienced pluggo user [since pluggo 2 in Dp 2.7], so i have all i need to reinstall, i just don't want to spend the time!
regards

DP5.12, Pluggo 3.5.4[because it supports my favourite 3rd-party plugs], os 10.4.10, dual 2.0 G5, 4.5GB RAM
