Hi @edmario54 when you updated Photoshop - did you have "Remove Older Versions" preference on? If so it would have removed the older version when updating to the current.
As for your plugins and filters, check for your plugins in the proper folder: Program Files\Adobe\[Photoshop version]\Plug-ins
Since you've upgraded there are no guarantees that plugins are updated to support the new version of PS as well. You'll need to check each to make sure its compatible with the current PS build or if there are available updates.
