Yes, there was an error in one driver version and some versions of Vista could not use the driver we’ve supplied. Anyway, this should be fixed now – please download latest Moncha from our web and after you install it, there is a drivers directory in C:\Program Files\Moncha – try to use this one and please let us know, if it’s working.
We’re sorry for inconvenience and thank you for helping us solve it.
