BRX hell

Now, this is incredible - I have a BRX application which worked well until yesterday - and since then it can not be loaded into Bricscad after compile. I've tried everything I could possibly think of, and whatever I try I get only * (arxload) : can not LOAD file

This morning I succeeded loading it once, but I am not sure what was changed, since MVS crashed after that, and all later attempts are also unsuccessful. Any ideas? I've tried to compile BRX sample and it can be loaded without the problems.

I have checked project properties and compared to BRX sample, and they are all the same. The only difference is that my dll is linked with sds.lib, since it use sds_bbox, but it worked well in the past.

All needed functions are also exported (acrxEntryPoint, acrxGetApiVersion, odrxCreateModuleObject and odrxGetAPIVersion).

Does anybody have an idea what to do?
