So I was crunching along and suddenly I got the a fore mentioned error....After getting this error POEM would not download tasks at all....I visually checked that the app_info filename and the POEM app matched i.e. (poemcl_1.3_windows_intelx86__opencl_ati_100)...Vi sually the app_info & poem app filenames looked identical...however I copied and pasted the string name from the POEM app into the app_info file and now everything is good. I guess somehow the filenames were not identical....hope this helps someone looking for a solution to this error.
Update#1 : On second inspection it looks like the filename might be unrelated...On my other machine I just had to keep moving the app_info in and out of the project folder and restarting boinc...Then POEM finally begins to act right and downloads WU after about 10 restarts...
