I can't seem to convert from a new assembly to an older one (WS245 to WS220). However, when I reverse the release1 and release2 (WS220 to WS245) using the same file it seems to be functional.

Only forward. I tried messing around with it for a while, but I couldn't get it to work. I'll try to update this soon making that clear. What are you using that is WS220? \r\n\r\nIn the end - it was easier for us to move everything forward rather than move some things back."}}
