I have now managed to replicate this error one one of my PC's, also reported above by Greygor. Can you please try the following fix on your PC and see if the wallet runs afterwards: 

1. Close the wallet.
2. Check the file size for 'ballzcoin.exe' in the following folder: C:\Users\your.username\AppData\Roaming\Ballzcoin-Ballzbrowser-Wallet\binaries\ballzcoin\unpacked
3. If the file size is 0MB, delete the exe file (don't delete anything else!).
4. Download the Windows client binary in the announcement post, extract, and copy ballzcoin.exe to the folder to replace the deleted file.
5. Start the wallet. Does it work?

If this solves the issue, I will investigate further before creating a permanent fix.

Good suggestion!
If MPH doesnt add Decred, it will loose a lot of the Claymore dual mining crowd, since they wont be able to dual mine ETH+Decred here as opposed to eth+sia.
A friend of mine just switched over from MPH due to this reason

What are some good pools to try? I'm on EasyHash but with only 157 ETN mined in 24 hours with 4100H/s it feels not right.
