The exporter was written for 1.24 - you are using 1.25 - but this shouldn't cause an issue... but have you tried it with the 1.24 version of Octane with the same results ? The issue that your link referred to was to do with 3DWH's files having some odd file/material naming... I fail to see the relevance... Did you set the Exporter's dialog setting to export the Camera as well as other settings ? Post a screenshot of the dialog you use and with which you don't get the result you expect...
The difference between 1.24 and 1.25 is not dramatic. The exporter made specifically for 1.24 should work the same with 1.25. I have just tested it and it works OK for me. Your screen-shots were not attached properly. Is the blue/Z axis 'up' in the SKP ?
