I just downloaded the service pack 4 for solidworks 2014 and installed it using the solidworks installation manager to install it and had no issues. then when i went to open a part, which i had all my parts located in a windows library folder entitled Solidworks, it restricted my access to the folder itself and deleted all of my parts and assembilies that were saved there. I checked the recycle bin and found some of them but other parts i cannot find anywhere on my computer. I tried restoring the folder/library to a previous versions but there were non to be found. I really need some help here i had over 60 parts alone in that folder many of which were components to an assembly that are now useless.
