Is there a way to go back to ver 5.01; 4.98 screws up Object Dock

As others have reported, version 4.98 of IP5 cause many of the icons in Object Dock PLus to go to a default (text) image.

Unloading IP5 ver 4.98 resolves the problem, but now I have no IP.

Is there a way to re-download and reinstall the 5.01 version of the program through Impulse? Right now, all I see being available is the 4.98 version which is incompatible with ODplus.

Or can I simply utilise the 4.21 version of IP available through impulse?

I am running Win7 Hmoe Premium 64-bit. From what I can see, ver 4.21 would not work for my machine.
