Hello,
We released EigenD 2.0.54 last night but discovered a regression bug that was introduced at the last minute, so we decided to pull the release this morning and will put up a new version with a fix up later.
The bug in 2.0.54 is located in the save setup behavior, it prevents more than one successive save to take place. As soon as you saved once, any other save will be prevented since EigenD thinks it's still busy saving.
The people that already downloaded 2.0.54 should be aware of this and we recommend to go back to 2.0.52 until we put up a new release.
Sorry for the inconvenience,
Geert
