Основной совет - давно пора переходить на другой язык и средство разработки.
"At ArcGIS 10.1 there will not be an ArcObjects VBA SDK nor will new VBA development with ArcGIS for Desktop be supported. There will be an optional separate setup for legacy VBA support in the ArcGIS applications. This will require an additional licence authorisation similar to ArcGIS 10.
VBA will be available if needed so existing solutions can continue to work while the code is being migrated to .NET. We recommend all users with VBA code start migrating now to an add-in or custom extension using the ArcObjects SDK for .NET or Java. This is the end of the support of VBA as a development or customisation language for ArcGIS."

Т.е. (скорее всего) у Вас где-то в проекте осталась "битая ссылка" на библиотеку.
