So this problem began maybe two or so weeks ago:

It really started when I was trying to trade BitUSD. At first, I was trying sell my BitUSD after blindly missing the "insufficient depth" banner. After noticing it, I tried cancelling my sell order, but even after multiple tries of trying to and 30+ minutes of it just saying "Canceling...", the orders did not cancel.

So while I'm stuck with the open sell orders, the next time I restart my client, I see that the transaction scanning is stuck at -100% and my transactions stuck at "Updating transaction history...". That is, I cannot receive or send any BTSX whatsoever.

Each time, I made sure I was using the most up to date client and I had kept backups on my computer in case something went wrong. The problem is that the client kept crashing the second after I clicked the icon and it popped open. Now I'm stuck with my updated client 0.4.13 and transaction scanning stuck at -100% and my client not really working.

What should I do?
