scan v7.5 messed up

[dian]

i have learned long ago not to play around with this fragile software and not to touch any of the setting adjustments. but yesterday i nevertheless decided to change the black logging screen to white (to be able to print screen). while that was successfull the following happened:

- pids (f8) is empty
- data (f9) is empty
- dashboads c is blank
- chart properties is empty. i can click on an empty space and a pid appears, but scale/font are empty and wont accept any input.
- other stuff stopped working, e.g. display ... (f1) opens some unrelated adobe document.
- time stamp disappeared

closing and reopening a file doesnt help, same thing. all new files are like that. previously open log-files i didnt touch work as usual.

i then attempted the same on another laptop and weirdly enough exactly same thing, the newly opened files are useless.

what happened? what can i do to make the logging software work again?
