internal software error

Hi,

I'm having some problems with internal software errors when I try to Preview my project.

Having looked at other posts I have made sure I have no overrides in my project but if anything this makes the problem worse.

With the main timeline End Action set to Return to Last Menu and Override set to a specific menu:

internal software error: .EditorTemplates.cpp, line 698

With main timeline end action set to return to last menu and override not set:

internal software error:.NavulatorCTimeMapBuilder.cpp, line 71

Then when I click on OK I get this error message:

internal software error:.PlansTitlePlanVIDEOTSLayout.cpp, line 828

which typically repeats about 6 or 7 times.

The same thing happens with the main timeline end action not set and override not set.

Check Project reports no errors.

My project consist of one long avi file, and the whole thing will (just) squeeze onto a single 4.7GB DVD after transcoding when the project is built.

I have set four chapters and have a single menu with a Play All button plus separate buttons for each of the chapters. These separate buttons are linked to the Chapter Playlist while the Play All button is linked to the main timeline. There is no End Action set for the last chapter.

Any suggestions/ideas?

Many thyanks.
