Drag and Drop ms file error


Have a strange error coming up after i drag and drop an ms file into 3dsmax window.
The content of the ms file is irrelevant as the error gets generated on the most basic ms file like

print “something”

i tried the following and the both work fine

dragAndDrop.dropPackage 0 [100,100] @“path\TO\msfile.ms”
fileIn @“path\TO\msFile.ms”

but if I actually drag and drop the ms file it gives me an error

MAXScript FileIn Exception:
– Unknown system exception <<

tried different directory destinations, no luck
However this seems to only happen to ms files , max and image files still work
