I would recommend that you switch to this DLL to avoid delaying your project creation due to an unrecoverable error. Unfortunately, for this you have to write new code analogous to yours from scratch.
There is a good in HTML reference book for DCX. You can find his it on the internet. The latest version is desirable, or at least for DLL v1.4.1 and higher. The difference is in some fixes and command changes.
Taking advantage of free time and with a little diligence, you can easily learn how to write code using this DLL and then it will bring the fruits.
