Hopefully you can suggest a way for me to get Ninja working again. The system changes were:
1. Installed Ninja 7.13 (had been 7.12). I doubt this is the issue.
2. I have Visual Studio 2010 Express installed on my system for a long time. I was going through the installation of VS2012 Express, which may install new versions of .NET, which could be a problem.
3. Some of my strategies have Reference to Encog (encog-core-cs.dll). I changed from an older version (3.0.1) to (3.10). (this is likely the source of the problems).
Attempts to fix the problem included:
1. Removing the Reference to the old dll, then adding it back (I have put the new dll in the same location as what the old one was).
2. Restarting Ninja several times (once for 32b mode, several for 64b mode).
3. Rebooting the PC.
Other notes: I get the error message for most strategies, including ones I've not edited (see SampleMACrossover log below). I had been seeing it in a few Indicators, but I 'deleted' the sole indicator which had any reference to encog. Note that most (maybe ALL) of the strategies which emit this error message have no mention of Encog in their source code. (They do have the reference to Encog, as all strategies seem to share a common set of references).
Thanks for your suggestions. (or tell me what other info to gather to help toward a resolution)
