Uploading a code plug to the GD-88, I was getting the following error - much truncated - "... System.ArgumentException: Offset and length were out of bounds for the array or count is greater than the number of elements from index to the end of the source collection at System.Buffer.BlockCopy(Array src, Int32 srcOffset, Array dst, Int32 dstOffset, Int32 count)... ".
Turned out to be an error created by Libre Office spreadsheet software. Switched to genuine MS Excel (2007 Office - no less). Loading exports into Excel, saving from Excel, reloading Excel generated file into the Codeplug Editor cured the upload problem.
So beware non MS spreadsheet software. YLMV!
