Repair Geometry Failed

[SydneyHeathcott]

When I trying to use the Feature to Raster tool I get these horizontal streak lines, another post said that the Repair Geometry tool should help to fix this and when trying to run the Repair Geometry  tool I get this error message

999999: Something unexpected caused the tool to fail. Contact Esri Technical Support (http://esriurl.com/support) to Report a Bug, and refer to the error help for potential solutions or workarounds.

I tried pulling the feature into a blank project to run in case it was an issue with the project and the same thing happens. I then thought I'd try to go a round-about way by doing Feature to Polygon then Polygon to Raster, but Feature to Polygon failed with this error message

160196: Invalid Topology

unfortunately, the errors are with data i need. I've attached a screenshot of what the message looks like, i'm starting to think it might be a bug and not something i've done. I'm going to try to go back to the 3.3 version and see if that makes a difference bc i've exhausted everything i know to try

well short segments and self intersections as the error states, 

If you could select a few of those and export/save those to a new empty geodatabase, maybe the trip to a new home will make them better, If not, I wouldn't waste any more time since nothing has helped apparently and Tech Support should be better equipped to deal with issues like this.

this is an update - I downgraded back to 3.3 and started my project over and it has fixed this issue.
