Perhaps they are saved in a newer version of Pes than your software or machine can recognize...try another format and convert it to pes and see if that works...
I downlaoded them with no problems.
Ms. Veronika is working on the problem. Send a PM to the moderators jrob,mops,martine,marjialexa,explaining the problem.
I have just right clicked on the pes format on all the new bunnies and it downloaded NO problem.
