AutoCAD Architecture :: Model Space Colors Missing?

We have a bit of an urgent situation at work. Namely we have stepped over from standard AutoCAD 2010 to AutoCAD Architectural suit 2012.

The situation is as such that if we set our search path to our ctb and our dwt (nothing else no other search path changes) our dwt templates load as being visibly black/white all the colour information is wrong.

Upon closer inspection of elements draw in the dwt for example a line though it still displays as being physically black/ white the properties menu declares it as being the colour we need it to be for example red. We have double-checked in our plot dialogue box if the ctb is present and its presence is confirmed. The peculiarity is though if we try and locate it using our (findfile “CTB\NAME\AND\PATH” method the command prompt returns nil meaning as far as I have come to understand as missing/ not loaded/ not found.  A line the properties menu states the plot style is set to ByColor and not by the specific CTB file as when the same line is selected in AutoCAD 2010.

We have quite an extensive customisation comprising almost of every kind of file AutoCAD has put up for user customisability so my instinct was that something within the whole customisation was causing our issue.

We have since rid of all customisations and reset the profile using AutoCAD and as double backup also via the registry keys, we also have deleted our corresponding AutoCAD application folder in the hope of eliminating some nasty that may of stayed behind.

We have no plug-ins that cannot be the problem. Further experimentation shows that if we create a search path using the following lisp the colours are displayed right for the duration of the AutoCAD session but upon restarting AutoCAD the colours again become black/ and white.

When entities such as the lines are moved the items being moved flicker across the screen in their correct colour, once placed the image instantly shows as being black/ white again.

As final symptom our model space colour seems to be the only thing effected, our layout tabs are fine however we don’t work in layouts but rather in model space.

I have also as last used the vars2src command in AutoCAD 2010 and imported the variable settings into AutoCAD architectural suit 2012 hoping that the issue was a variable setting overlooked, to no avail though. Neither is our desktop icon enabled with any switches such as profiles.
