My Microsoft PowerPoint 2010 encountered problem with edited theme file
Indeed some strange errors happens but there is solutions for it. Why don't you try in this way. First you must launch Power point 2010. Then you access the design tab of the ribbon. After doing this you must locate the themes group, select the More button in order to see the Themes gallery in drop-down mode.
Step two is to select Save Current theme, but don't let the name like that, you will provide a new name and chose another destination for your new theme file.
If you do all this steps it will work.
You think Microsoft PowerPoint 2007 is better because you know about its functions & work easily. Microsoft PowerPoint 2010 is also good but it has hidden function or we don't know about this. To fix this problem
1. You have to download theme.
2. Browse it in your power point themes.
3. Then save current theme in new path in new name.
As follow those steps you can fix this problem.
