I get some completed responses, but not many, leading me to think that the script isn't working for most people. I did receive one note from a worker: I can't open this Inquisit in either IE or Firefox and I get the following error message: "Script Url: http://www.millisecond.com/myaccount/scripts/eknowles/RaceCat/RaceCat.iqx WIC Error: 0xffffffff80070057 The parameter is incorrect. Line 762, File win\Direct2DGraphics.cpp Unable to load the picture 'http://www.millisecond.com/myaccount/scripts/eknowles/RaceCat/./W020-B080 R.jpg'. Verify the file is of a supported image format." Any ideas what might be going on? Thanks! Eric Tags inquisit-4

I would therefore appreciate to hear from you if Amazon is behaving the same in your case. Because as far as I can tell they are either extremely unfair or completely incompetent. I mean Inquisit has been used in dozens of studies on MTurk, so their behavior very much puzzles me. Anyway, good luck for your study! Livio

Group: Forum Members Posts: 13, Visits: 146	Hello, Some of my participants encountered a similar error: icon Error unknown WIC Error: 0xffffffff80070057 The parameter is incorrect. Line 1015, File win\Direct2DGraphics.cpp I do not have any space in the names of files that I used. Is it possible that using an underscore in the name of the files might cause the same problem? Or is there any other reason? Thank you in advance for your help, IR

There's likely something similar wrong with your script. However, what that is cannot be answered in the abstract. You need to provide the relevant code.
