Assuming you have it here:
C:\bsp\pball2\quake2\pball\mapfiles
First, only use lowercase in map names and directories for bsp, it solves other issues.
But it also says it can't find your qvis3, which makes me think the file path isn't right, or you deleted the compilers. They should be here:
"C:\bsp\pball2\quake2\util"
"C:\bsp\pball2\quake2\util\arghrad.exe"
"C:\bsp\pball2\quake2\util\ArghRad200.exe"
"C:\bsp\pball2\quake2\util\arghrad300t9.exe"
"C:\bsp\pball2\quake2\util\qbsp3.exe"
"C:\bsp\pball2\quake2\util\qbsp3_original.exe"
"C:\bsp\pball2\quake2\util\qvis3.exe"
"C:\bsp\pball2\quake2\util\WINQBSP3.EXE
If it can't compile the .map into .bsp with qbsp3 then it obviously won't be able to load it later in vis.
