You need the Timebase.exe and Splash2.bmp files. Put them in the same directory as the DOS version so the data files can be shared. Put the others in your Windows/System IF THEY DO NOT ALREADY APPEAR THERE or if Windows asks for a new version of one of them. If you do not have VBRUN300.DDL download a copy from one of the forum libraries and put it in Windows/System. The file is usually called VBRUN3.ZIP.
