.tib files will no longer open within Windows Explorer

My .tib files will no longer open by doubling clicking them in Windows Explorer and the icons look like white paper. I tired editing Windows File Associations, but all this resulted in is Acronis app opening up. I use to be able to simply double-click my .tib files within Windows explorer and gain access to files within the .tib files. I uninstalled Acronis 2014 and re-installed, but still had the same problem. Then I uninstalled Acronis 2014 and run their Cleanup Tool for 2014 (atih_cleanup_tool_s_e), and fallowed all the instructions including the part about Regedit. Then downloaded the newest Acronis True Image 2014 (AcronisTrueImage2014_6688_en-US). Still same problem. Any help would be greatly appreciated. :)
