Typo in b. of Guenter´s answer :
delete xpti.dat, not xpi.dat (in the components folder).
Or else, if it is too difficult to handle for you,
you can also try my browser variation KM 1.0.1-ax .
Download links at the page for unofficial versions, here:

Don´t forget to get the needed additional .dlls
if you don´t have them already, as described there.
