I started using smartcoin (r451 ex) recently and ran into an interesting bug: instead of failing over to a backup profile, smartcoin terminates with the following message:

07/18/11 14:05:06       ERROR: It appears that one or more of your devices have locked up.  This is most likely the result of extreme overclocking!
07/18/11 14:05:06              It is recommended that you reduce your overclocking until you regain stability of the system
07/18/11 14:05:06       Killing Miners....

The thing is that it app fails at the very beginning when trying to connect to BTCguild using phoenix r111 while BTCguild is unaccessible. Perhaps this is because the meter doesn't show up until a connection is established? I'm running r451 experimental. Overclocking is not an issue here as everything is pretty much stock, with just my fans cranked up to keep everything as cool as possible.

Love your the work!
