Okay 1st you have to download NotePad++ and install it. Then Close LB go to your LB folder and go to Data\Platforms and open all your XML files. Then in NP++ go to search in the menu bar and go to find. This will open a new form in the find text box type in your path C:\Your\Path\Here once you do that then go to count and make sure it is finding your path. If it is then click the replace tab and type in your new path then hit change in all open documents and it should overwrite the paths in all of your xml files go up to file on the menu bar and select save all. Finally close NP++ and reopen LB hopefully it is all fixed. Before you do any of this make sure that you save a copy of your Data folder for a just in case scenario.
