Rubi 3 Usage?

After initializing Rubi 3 using my own code http://pastebin.com/nsLM4mMk same as the order listed in http://www.apmaths.uwo.ca/~arich/IntegrationRules/MathematicaNotebookFiles/MathematicaNotebookFiles.html, I got some disturbing results even in highlight tests: "$IterationLimit::itlim: Iteration limit of 4096 exceeded." with something like "Hold[Int[Rubi`Private`v$4716, x]]" returned. Some such tests are listed in http://pastebin.com/u7EP4uPJ

I guess these results may caused by following reasons:
* Since the order of DownValues (rules) added to a function will be matched according to the order, it's possible that I did initialization in a wrong order.
* Some functions in Rubi are unknown, although I modified the obvious ones like "sin"->"Sin", "Sim"->"Simplify", others such as "ExpnExpand" etc are still unknown to me. Is something missed when transfer from version 2 to 3?

Does anyone meet similar problems?
