Avoid using dots in file/folder names.
"Safe" characters to use are letters, numbers, hyphen, space and underscore. Other characters can cause problems as they can confuse the operating system.
It's going to be a bit tricky to salvage this project.
What you need to do is the change the name of the project to something that uses "safe" characters (for example "K-T-28-10-10"), change the name of the data folder to the same name (example "K-T-28-10-10_data") and then open the AUP file in a text editor (for example NotePad or NotePad++
) and replace every instance of "K.T. 28.10.10" with the new project name.
Make a backup copy of the project before you start changing things.
