Change from MLE 1.6.3 to CMSms 1.6.5

[leerraum]

Hi,

I've encountered one big problem at the final production phase of a site that should have been launched a week agoa. This problem leads me to the conclusion that I have to switch to the regular CMSms installation.

Problem:
I've used MLE 1.6.3, with Products, Orders, FEU and a bunch of other plug-ins. The orders module has an obvious bug, when I'm not logged in as admin and I'm calling the checkout page, it redirects me to the admin login. I've already talked about this problem here: http://forum.cmsmadesimple.org/index.php/topic,38247.msg180817.html#msg180817

Not solved:
I can't update the modules, because they require a newer CMSms version, which is not available yet. I read about the 1.6.6 hack, but you can imagine that I dont want to try it yet. (I tried to modify the requirements before the installation, the installation worked, but it didn't solved the problem).

The only solution I see here is to "downgrade" the MLE to a regular newer Version. Has anybody an idea how to do this, or how to solve the problem mentioned above?

Thanks and have a nice sunday.
