the screenshots are showing that something has blocked access or you have installed in a different folder/location.
you are running the profile from one location and mfp is trying to save in another location.
check the location from the error message to see if there is mfp located there, if so try running direct from the location, and then create new profile from there.
what antivirus are you using.
Hi Mcbee
You were right! (of course)
Despite the fact that i had allowed everything to go to default location, the uninstall had not taken out all the different incidence of the program and it was writing to an old install.
So the program is not actually dissapearing now, however we are now left with the program operating the triggers perfectly for about 10 minutes before it gradually grinds to a halt and stops.
I tried to separate the triggers into two blocks of half the size and run them on two different accounts, and take out all the non related races for each, but it still produces these blank screens after around 15 minutes. As i type 1 platform has crashed the other is continuing but now I see from the task manager that the other has crashed also, but both are still visible.
As i mention in the initial posting there seemed to be no problem with the original install which ran for about a year with no problem. Any other ideas?
i am running KASPERSKY anti virus by the way
thanks again Mcbee you are a legend!
