Reinstall 10532 after rollback to 10240?

I installed the 10532 build over the release build (10240) but had some odd issues with memory usage being very high.
I rolled back to the 10240 build but have since been asked elsewhere to run some diagnostics, so I want to reinstall 10532 so I can do that.
However Update is no longer offering this build to me. I am still in the Insider Program. I even tried removing the PC from the Insider Program, and then adding it back in.
I also cleared out temp files and the Software Distribution\Download folder, and the $WindowsBT folder.

Any other ideas?
Does the Insider Program assume as I rolled back I do not want to use that build?

If you have what Wynona posted and you are not getting an update just keep trying. There is a possibility that MS has removed 10532 in prep for build 10540..?

Yes, my update settings show the same, with the addition I have chosen additional Microsoft Products updates. I initially gave it about 4-5 hours. When the update didn't show that was when I removed the PC from Insider builds, rebooted and joined again. After that I left it for around 24 hours.
I'll try again tonight.

OK, thanks. I will try that later. Thinking back I am not sure when I ticked that, so it could be after I rolled back.

I think it is a good idea when a new build is received to create an ISO file from the ESD file and stash it somewhere. That way I can always upgrade to the newest build if something should happen.

Just to update that I was unable to ever get 10532 installed again, but it has now given me 10547, so maybe it had been removed in preparation for the new build.
As suggested also created an ISO from the ESD file now.
