Visionaire archive extracting not work

[chupachupbum]

When using UniExtract for a game built with Visionaire Engine, the tool still recognizes the engine but cannot output anything. It changes the data.vis file to vi extension, which may because I check the "fix error file format..." when running the tool for the first time.
The game is Countess in Crimson, using Visionaire Engine version >= 5.1.7.
When I look at the source code of the UniExtract, it uses Vis3Ext to extract Visionaire, and it is from Deniz Özmen's work?
