Quote: No I am not a pro but I use the camera for my business when I can't get a pro or it is not worth it so the results need to be professional and while have learnt that "a workman should never blame his tools', having the right tools can make the job so much easier.
Well, when your tool crashes when you click on a button and when your tool causes your camera to lock up and requires removal of the batteries to fix, I would not hold the workman responsible.... unless that workman keeps trying to use the same tool with the same results over and over again. A few tries in a row, and reading reports of similar "tool" behavior from other users and I am going to blame the tool. :-) :-) :-) :-) :-) There is NO WAY I am going to risk locking up my camera and risk losing images in front of a customer. :-(
Anyway, do you need all of the tethering options that the software is trying to offer?
Could you get away with Eye-Fi wireless card, (or now Transcend and a few other brands that now offer in-card WiFi)?
These cards only allow transfer of photos from the camera to a PC/Tablet/Phone, and do not allow control of the camera itself.
But for my work, and likely for most photographers, that is the only tethering feature needed to begin with, so those might be the perfect option.
Otherwise, as other suggest, you might try PK-Tether. It is an individual's attempt to make something work for nearly all models of Pentax DSLR. You may find it more stable than Pentax's software even though PK-Tether is
