I will update Slimcoin AIO package for Windows. As I see my old package doesn't work anymore, probably due to new version of client.
Still those synchronization is pain in the ... Ah, if it would really get an update to anything newer than this 0.5 btc codebase, it could at least be somehow functioning without hiccups.
I think you'll need to compile v0.6 if not I should have a compiled version (I can send it to you if you need me to).
An upgrade is indeed needed, that's the key issue we have to solve.
I have 0.6 version from compiled by Graham.
Besides is there still problem with mining on 0.6 version? I had such problems when I tried it 2 years.
I don't really know, since I'm not mining. If you can try it to see whether the mining works or not and report here if there is any issue we can try to find a fix.
We are also actively looking for the solution in order for us to have an upgrade.
