Hello,

My version of Software:

 - Trados Studio is 15.2.0.1041

 - dll Sdl.ProjectApi.AutomaticTasks.Conversion is 15.1.0.0.

 - Adobe Reader DC 19.021.20048

When i try to run the Task through API:

AutomaticTask task = createdProject.RunAutomaticTask(projectFiles.GetIds(),AutomaticTaskTemplateIds.ConvertToTranslatableFormat);

It freezes on the converting step:

2019-10-23 14:06:42,256 DEBUG ProjectApi.AutomaticTaskExecuter - Executed: project=2ccaf774-eae6-4db8-803c-782e39b7e782, task=Scan, duration=0s

2019-10-23 14:06:42,678 INFO ConversionTask - ProcessFile: converting file

Doesn't convert to sdlxdiff file, but when i try to do the same process on the Trados Studio it works.

I disassembly the dll and see the line of code that freezes.

Class Sdl.ProjectApi.AutomaticTasks.Conversion.ConversionTask

FileTypeSupportUtil.ResolveLanguages(converter, executingTaskFile.ProjectFile.Project.SourceLanguage, null);
executingTaskFile.LocalFilePath = filenameWithDefaultExtension;
this._log.Info("ProcessFile: converting file");
converter.Parse(); -> This one and don't throw exception

Thanks for the attention
