Dot Probe + win XP + DirectRT2010

Hello,

I've, made an experimental file of a dot probe task and got it working perfectly on my PC laptop, on which I have window 7 and DirectRT 2010.

Now I put the same file on my Lab machines, on which I have Win XP and DirectRT 2010. On these machine, DirectRT can't run the .cvs file. When I try to run it I first get the following message:

---
11 System.IndexOutOfRangeException: Index was outside the bounds of the array.
at . . . ( & A_O, String[] A_1, Int32 A_2)
---

Followed by:

---
Problem in: DirectX.2
System.Exception: No compatable resolution was found.
at . (Int32 A_0, Int31 A_1, A_2)
---

I guess it has something to do with the resolution... but I have no idea how to fix it.

Thanks for your help.

I just checked and I just realized that I can't run any sample file with Direct RT on the machines with winXP + DirectRT2010.

For instance, if i try to run the modern racism file I get:

Empirisoft executeDRT
15 System.InvalidCastException: Conversion from string ".5" to type 'Single' is not valid. ---> System.FormatException: Input string was not in a corret format. at Microsoft.VisualBasic.CompilerServices.Conversion.ParseDouble(String Value, NumberFormatInfo Number format)
---end of inner exception stack trace---

Update Nov 8th:

I got DirectRT2010 working on the 4 win XP machines.

Now the problem is the dot probe task. When I run the task on a machine that I have downgraded to DirectRT2008 it works perfectly, however, DirectRT2010 displays the two dot probe stimuli (either images or words) overlapped in a wrong position of the screen (in the upper left). I got the same style file on each computer.

Do I have to downgrade all machine to Direct RT 2008 or there is something I can do to have the same dot probe file running properly both under DirectRT2008 and 2010?

Thanks for your help!
