argh so if i install all my maps will be black again?
No, your maps will
not be black again.
The black map bug was a potential problem under certain circumstances in the
1.33 patch, which was not available that long. The current/last
1.34 patch fixed that problem, so you should not have any issues installing the patch and continuing with your existing save.
If you want to play it safe, you can zip your saved game folders, install the patch, and then and un-install / re-install without the patch if you run into any problems. Each save is a separate subfolder in the '
..\Divine Divinity\Run\savegames' folder.

It is highly unlikely that you will run into any problems due to installing the patch.[/color]
