Fix for "The version of the server you are trying to connect to is not supported."

Question

Like many of you, I experienced the following problem with Lion:
"The version of the server you are trying to connect to is not supported. Please contact your system administrator to resolve the problem."
I googled and found a workaround for that. It worked for me, maybe worth a try:

Same problem here, and the above fixes do not work. I'm running 10.7.5, and the defaults write commands do not appear to work: the plist reverts to its default state after each connection attempt.
I can confirm that the correct values are entered in the plist immediately after performing the defauts write commands (while logged in as root) described in those links, by opening the plist file in xcode. But regardless of rebooting or not, the file immediately reverts to its default values as soon as an afp connection is made. Extremely frustrating. The "defaults write" simply doesn't stick.
I desperately need to pull some data off of a Mac IIci that is running Shareway IP under System 7.5.5. This always worked seamlessly in 10.4 though 10.6: I really need a working solution for 10.7. Thanks for any help...
