I've suddenly started getting a System.Security.Cryptography.CryptographicException when trying to load line files in STHS 2.2.6.

Code: Select all

Exception Type:
    System.Security.Cryptography.CryptographicException

Message - Source
    Padding is invalid and cannot be removed. - mscorlib

Occurring on 32-bit Windows 7 Professional w/ .NET Framework 4.5.2 (previously 4.5.1). Same system I've been using for years, and I've been using 2.2.6 for 3 weeks without any issues. An automated line load ran successfully today at noon EDT, but the automated (and now manual) simulation has failed. I've ruled out issues with the line files by restoring some of the successful files from earlier and attempting to load them.

I also tried reverting to version 2.2.5 and got the same error.

The file you are trying to load is corrupt.

The file you are trying to load is corrupt.

It's happening with all line files, even the ones that had successfully loaded 7 hours earlier.

That's really strange. I uploaded a fresh copy of my line file and it loaded properly. I'll write it off as a one-off. Thanks SImon.
