Error message: Assertion in line 1358
 

After installing Pro53 RTAS and the update to the latest version of Reason adapted, I can't use PTLE anymore without getting the following error:

Assertion in
"\code\aztec_Staley\AlturaPorts\NewFileLibs\Bdm\BD M_Work
line 1358

This happens to me on both of my machines. With Mbox2 and 002R. The only difference: on one system, the message is ... aztec_Lomax...

The warning message always pops up when returning (setting focus) to the PT window from i.e. Reason etc...

Is there anyone who can tell me the meaning of this error message? Or at least where it comes from? The hints in the message seem to be for PT's programmers only...

Thanks,
Holly
