Error Code #1

[Deleted]
While running my EA, I occasionally get an error #1 when trying to make a buy or sell. After which, it fails to continue trading. What does this error mean, and how do I go about fixing it? Thanks -Shane

"OrderModify attempts to replace the values already set with the same values. One or more values must be changed, then modification attempt can be repeated."

But I'm not doing any OrderModify calls - it wouldn't be caused by trying to make a trade at a position where a trade already exists would it?
what the build number of the client terminal?

Do you think the difference could cause a problem like this? I don't really need to know exactly what causes the problem, as long as I can recover from it if it happens. Do you have any idea how I would do that?
Please download last build.

If problem remains report please about it.
