Notes/Domino 6 and 7 Forum : NSD is running

I have upgraded many pc's from Lotus 5.0x to 6.01, all went fine except for one pc. The situation is that she opens Lotus and after about 20 seconds, it gives the error message about NSD is running, gives an error log message and then the only choice is to "OK" and let Lotus crash. Outside of some info at the top and the bottom of the log, it looks pretty Greek to me--but I am including some of the log information that may make sense to someone......

****top of log*******

There is more in between if anyone is interested. Any thoughts on this problem would be greatly appreciated!!!
