Hmm, since upgrading to latest version, I get an Unhandled Exception error (.net) when trying to start my x11 miner.

Multiminer runs fine and shows my 3 network devices ok, but If i hit start to mine on my previously working R9 280X I get the error. (Running SGMiner 5.1 specifically setup for the 280X)

Code:

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

Unfortunately I'm out of town so I can't dig too much to help, but it looks like you have two GPU algorithms defined with the same name. Either try editing them in the Settings or viewing / editing the AlgorithmConfigurations.xml file directly to remove the duplicate.
