unusable backup

[Warbarque]

Hello,

After changing computer, my game save doesn't work anymore. A ship gets stuck on the launch pad without me being able to remove it and an error message then an exception message appears in my console. When I launch the save game, no button works anymore, even the return to the menu but the mouse cursor moves normally. I would like to recover this backup, do you know how to do it? Thanks

The error message writes : "Exception : ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.

Parameter name: index"

The exception message writes : "Error: Exception handling event on GUIRecoveryDialogDespawn in class LaunchSiteFacility:System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.

Parameter name: Index

at System.ThrowHelper.ThrowArgumentOutOfRangeException"

and many other "at": at vessel.get, at Flight State, at Game Updated, at GamePersistence.SaveGame, ... 

Do you know how to resolve this ?

Thanks a lot
