Ever get this message? Well, simple enough this occurs when you are attempting to open a file that has been created in a newer version than the current version you are using. For example, opening a PSPX file in PSP9.
It looks like this:
The problem with this particular file is that I saved the original file while using PSPX. So, to correct this problem, I will open PSPX and open the original file. Then I will save the file and change the options following these steps:
1. Select File Save As:
2. Select Options at the bottom of the save dialog box.
3. Press the arrow next to the Version
4. Select the version compatibility to save the psp file.
I generally will select a lower version than that which I am working in. This is especially true if I am saving a file that I want to work across all versions.
Hope this helps to correct any errors you may be encountering!
