This is free/non commercial/open source software. But people expect 24/7 support. There is no other funding. Only in the form of donations. But nearly only very few donated.
Although it took many hours to develop Vertigo, only very few donated. You can see amount of donated here:
https://explorer.vertcoin.org/address/VertGv5nVwYYR7mTmDDeAP9et1NJyAsC9P. There is just 0.03 VTC!
So if you want to keep my motivation of giving helping hand to users and provide updates of this software, something really should happen from user base in return.
I normally charge around $25 USD per hour by providing such technical support.
Hey now, I wasn't "expecting 24/7 support". I was simply asking the collective knowledge of this forum for help. Plus I assumed bug reports would be a good thing, especially if you want to stabilize the app enough to where people will actually feel safe using it. Hopefully I'm just misinterpreting your message, but it sounded to me like you were demanding payment to debug your own software.
Anyways, I'll dig through the log file you mentioned for anything obvious myself. I'm offering my help debugging here if you are interested. I haven't touched Java since college, but I've got 10 years of professional experience as a developer, so I can probably debug better than the average person.
As for the donations, what exactly are you expecting? CryptoCurrency in general is still not in widespread use, alternates to Bitcoin are even newer and more niche, Vertcoin is only a few months old, and your software's life is measured in weeks at this point. So your user base is incredibly small, and from the looks of it many of those users are having problems. You can't expect users to donate when they can't even get the wallet to work in the first place! Even if everything works perfectly, very few people will ever donate. Thats just the way people are. You need truly massive numbers of users to ever generate much from donations alone.
