We saw something similar at this same version (not sure about PU, though) but it was with a standard register during the sales journal update process. For whatever the reason, the reports would not display on screen. We simply copied the reports from a stock test system and put them in place and they worked. We were guessing something during the conversion process messed up. Very strange. Perhaps you could simply copy the old form back over top and re-convert it to the latest version???
