Help S3 4.3 problem

Just updated my galaxy s3 to android 4.3 and after the update everything seemed fine until I went into s memo and found that all my memos are gone. Did a bit of searching around in my phone files and found that they were still located in the cache of the s memo file. The problem is that they're in .sfm format and I can't seem to recover them. Was wondering if any of this seems right to anyone and if there is anything that can be done about it.

also phone isn't rooted

What it seems is another bug to add to the already huge list of bugs for the 4.3 update. I think we have a thread for that in the S3 section.
