Hi. Thanks for your message and sorry about the trouble. We're working on an updated wallet. In the meantime:

[Note: back up your wallet.dat file before you do the following. It is in your appdata\roaming\karma\ folder. And just to be safe, you might as well make a copy of that, too]

1. Close the wallet, then create a text file: c:\users\YOUR-NAME\appdata\roaming\karma\karma.conf (or on linux, ~/.karma/karma.conf) and paste the following into it:

addnode=67.173.120.250:9432
addnode=91.153.109.149:49522
addnode=78.214.167.61:11081
addnode=69.130.152.117:51308
addnode=96.230.110.235:9333
addnode=128.173.185.170:9333
addnode=45.55.176.26:9333

2. Delete everything in %appdata%/karma except wallet.dat and karma.conf

3. (re)start the Karma wallet.

let us know if this doesn't work.
