I purchased the Retail copy of U-Boat Missions today. I had had to reformat my HD recently so SH4 was no longer on it. So I re-installed my retail-bought copy of SH4, patched it with the 1.4 patch then tried to install the Add-on. It started patching to 1.5 then I got this indecipherable error message basically stating that some file was un-executable and the installation failed. I then tried just running SH4 but it wouldn't run at all. Was it because I had not run the game before applying the patch then the add-on or should I install over a clean un-patched copy of SH4? I'm at my wit's end and Ubisoft's FAQ doesn't cover this (and their Message page is down). Any help would be great. These are Retail copies purchased from game stores with no Mods installed either.
