Well...everything has an upside...getting turned back at Sixola, started the trek back over the mountains to Paso Canoas...a beautiful drive at least...we really like Volcan so decided to stop there for a night or two...found a place to rent there so will be in staying in Volcan for a few months (thats the up side).
Drove to Paso Canoas and walked over to the CR side to try and sort out the paperwork...left the Jeep on the Panamanian side just in case CR did not want to play nice. All went smoothly...a couple hours and $20 later it was all fixed.
For the future reference of others the paper work problem: When entering CR (and many other countries) you must complete a temporary import permit. You must also cancel this permit when you leave the country. If the permit expires and the vehicle is still in the country then you have a significant problem, big fines, and siezure of you vehicle. In my case we somehow overlooked canceling the CR temp permit when we crossed to Panama (most of the border crossings in Central America are a bit chaotic so easy to miss something). Fortunately, I had a good paper trail to show that the vehicle had indeed left CR before the permit expired and was now legally in Panama...so a few conversations w officials and much shuffling of paper and the problem was fixed. If you dont feel comfortable handling this paper chase on your own then there are guys you can hire at the border to help you (they will find you). At the CR-Pamama border many of them speak English and will work for a fair tip of about $10 for a normal crossing. Most of them seem to be good guys...as opposed to the hustlers who work the borders around Bahia Fonseca (El Salvador/Honduras/Nicaragua) who are mostly interested in ripping you off (being "gringo'ed" we call it).
The down side is now I am comitted to driving back...my plan B if I could not work out things at the CR border was to put the Jeep on a ship and send it back to Guatemala...no more expensive than driving and WAY easier, but first we're gonna chill out in Volcan for a couple of months....ahhh...
