Windows Lve Photo Gallery

For some reason Windows Live Gallery keeps on increasing my single photos to three or four of the same. I have tried in settings to stop sync and also tried to unlink my pc. It has completely messed up ALL my photo files and has done it on two computers! How do I get back to how it was,  seems only done it since Microsoft did update and asked me to sign in and then my photos gone from Window Live Gallery to different places on my computer. I tried system restore on one computer but did not help and caused me a lot of work all to no avail.  Really fed up of the issue!
