DAS Plugins make troubles with Cubase (v5) in XTC-Mode

[rhythmaster]

I made a project and had several SCOPE-Instruments and DAS-Plugins (DAS-2A-ST, ...) included.
After restarting my project after approx. 3 weeks all XTC-Plugins (also the Inferno Synth in a "Instrument-Lane") were replaced by the
A550 EQ-plugin - but without a GUI when opening it.
I deleted the A550-dll from the Cubase-VST-folder and after a restart the next DAS-Plugin was loaded in all slots (N1084 EQ).
After deleting all DAS-Plugins and the TransientDesigner (which was also loaded) a missing-instrument pop-up appeared in
Cubase saying that the DAS-2A-ST (a fab plug!!!!!) was missing for all slots.

I have to re-construct the whole settings...

Is there a known issue with DAS-Plugins in XTC-Mode??

Win XP SP3 (all updates)
Cubase 5.1 (latest version)
SCOPE 4.5 in XTC-Mode (with Pulsar, Pulsar-XTC and Luna II without XITE-1)
Intel-DP35DP

Thanks
Harry

everything working fine here.. I use Reaper, Tracktion and (mostly) Sonar in XTC mode.
all the DAS are in there

In general all works fine with it.
But it happens sometimes after a Cubase-Update.
But now I had no update of any software/hardware.

Is it possible to edit a Cubase-Project outside of Cubase?
Just to correct the plugins??

'would be great but not that I know about (but to disassemble the file format by yourself)...

you may need to reenable the plugins in the Cubase plugin information window.

Gary's answer looks like a rational explanation for your problem ( definitively better than reverse engineering the cubase .cpr file format )

[rhythmaster]

you may need to reenable the plugins in the Cubase plugin information window.

I did this already --> no solution.
I also ran the installer of SCOPE 4.5
I'll try a few other things (de-install and re-install of SCOPE v4.5).

In the future I'll insert the plugins only with the MULTI FX Container and save the settings --> so then it's easier to rebuild the plugins.

Thanks
I'll keep you up to date.
