I don't know of any other options.
However, Suite Spot will need to confirm this but I just visited his download site and all seems normal there to me--are you going to http://www.aatranslator.com.au/ses2sesx.html for the download?
Just tried it and I get similar.
However, I don't know of any plans by Suite Spot to stop providing the software (he's only just changed it to freeware) so have to suspect it's a tech fault that'll be fixed eventually.
Come to think of it, I haven't seen him around for a short while so wonder if he's on holidays or something.
Sorry to renege on an offer but Suite Spot has contacted me privately
and asked me to not send out a copy of his software.
However, if you contact him via his site and offer a donation, he says
he'll send you a copy of the latest version.
(There might be an automated "due to lack of support I've stopped
providing this" message first but, if you reply to that with an offer to
pay, you should be okay.)
Reading between the lines, he's a bit annoyed at the lack of donations
and the hassles he's had providing support and updates.
Anyhow, sorry not to send it to you directly but I have to respect Suite
Spot's wishes on this one.
