error messages when opening model

[Anonymous]

when signing in or out of a teamwork model in archicad 11, i get the following errors:

- duplicated database name "roofmaker 2.1" at line 1 in the 2d script of file MASTER_GDLRoofmaker 2.1.gdl
- multiple versions - duplicate cleaners sink object
- Missing add-ons "cadimage update all" (i think this is because a mechanical/electrical engineer is hotlinked to the teamwork project, his machine has the add-on but mine doesnt?)

any way of sorting these messages?

Hello,

There must be a duplicate ArchiCAD library lurking somewhere in your project libraries;

0452J007 - Project Library
Material & GDL Library
SCC_LIbrary

If not found, drop them one by one and see the miracle happen
