can't locate local ip and startup delay

[fitchke]

[note from moderator -- the topic of this thread shifts below to a discussion of slow startup times for DirectRT v2010 when launched from within MediaLab]

I am running a csv file (dot-probe task) in direct rt (Version 2006.2.0.28) via media lab (Version 2006.2.39). The task will freeze up (light purple screen, no error messages). It most frequently freezes at the start of the task, but often also freezes midway through the task. When this happens, sometimes a data file with partial or no data is exported, but sometimes no data file is exported at all. The files are stored on a network drive, however both media lab and direct rt are saved onto the computers directly. The problem that we are having happens on all machines running the program and we have re-installed direct rt and media lab on all machines. We use media lab for other tasks and questionnaire batteries, and it only regularly freezes when we run a direct rt csv file through it. Any thoughts?

Sometimes when a file within the current experiment's directory is being accessed by another program, MediaLab and DirectRT will not be able to run properly.
Hopefully this solves the problem.

any tips on how I would figure out if another program is interfering? I don't believe I would be able to open the data folder while MediaLab and DirectRT are running (as is suggested here: http://empirisoft.com/Support/showthread.php?t=1795). They take up the whole screen. Is there a way to minimize the programs while the task is running so I can access the data folder?

Hm - this is possible in MediaLab; however not in DirectRT. If you're in MediaLab, simply run the input file without the main window maximized before hand.

The best way to solve this problem is to simply troubleshoot any possible programs that might be interrupting the flow of DirectRT or MediaLab.

Hello,

I'm using windows 7, media lab 2008.1 and direct rt2010. Media lab seems to be working fine until it has to transfer to direct rt and then all I see is a blank purple screen (no continue button). Direct rt never shows up. This is happening with several of my experiments which use direct rt within media lab questionnaires.

I am having a very similar problem with an experiment that one of our labs is trying to run.

Windows 7 running Medialab 2008 w/ DirectRT 2010. When MediaLab starts up executeDRT.exe ... the system hangs at the white/purple-ish screen for about 50 seconds before executeDRT.exe seems to finally pull up the experiment. We can then run the experiment without any problem. Is there anything that can be done to prevent this delay? I can't figure out what is causing it.

Occasionally, DirectRt says it "can't locate local ip" for authorization on startup, but I can't reliably reproduce this. This error has caused me some serious problems because it also occurs when Medialab (v2010) switches to a DirectRT (2010.2.103.1115) portion of an experiment (WinXP).

Do you have any hint what might be causing this? The network connection seems to be fine.
