how to restore SMS?

[mark5hs]

Alright so my droid just deleted my texts. I have all of them backed up to a gmail folder called "SMS" using Christoph Studer's SMS backup. Now how to I get them back on my phone? There's an app called SMS backup + that says it's backwards compatible, but I tried the restore feature with that (installed it, granted permission, then tried it), but it didn't work. Any advice? Thanks
