I have the save problem some other people seem to have. I try to fix it by changing the startup file like advised. However I can’t save the changes to the file. The properties state it is a “read only” and “archive” file and denies me access to change this. replacing the startup.xtml file with an edited copy also does not work. Does anyone have any further help? P.S. my windows account does not have any out of the ordinary symbols so this problem should not happen in the first place.
