you would have to be more specific about what errors you are seeing and what you are doing when they happen, panotour and pano2vr both work fine for me and both have great support teams and communities ;)
both apps have some features the other lacks so both are useful depending on the situation or maybe just your own interface preference, pano2vr has great patching feature and google street view support, panotour code is same as krpano which is well supported by very large community and can be adjusted with hand coding etc
