I get an error message saying "missing theme thumbnail" when opening a Prezi

Hi Zoli,
What Upgrades? From where? How?
Does Prezi Desktop Upgrade itself automatically? If not , I cannot see a Download link on the Prezi.com site.
Could you be a bit more specific when answering questions please?

I still have the problem. I am running the most current version of Prezi and of Adobe AIR (I get this problem with AIR 1.5.1.8210 as well as 1.5.2.8870) Windows Vista.

details from the error dialog box:
Technical details:
type: menuItemError the reason is: Event [MenuErrorEvent type=itemError]

In addition, some fonts have been substituted and after showing the prezi for a while and navigatiing around, the background turns grey (instead of white as it was originally). Help!

Sadly, I still have the problem. I tried uploading the prezi from the desktop to the prezi web and then downloading it again. This corrected the fonts, but the error dialog still appears. This is as you can imagine, very annoying as it looks buggy when showing a presentation. Please help! I love Prezi, but please correct the bugs!

I am still having the same problem. Could someone from Prezi reply, please? I would be happy to send you the prezi and I am willing to spend some time testing different solutions. Come on Prezi guys!

Hi Peter, and thaks for your reply, I appreciate it!
I thought updates to Prezi desktop were performed automatically when starting prezi desktop as soon as there is a new version? I have done a few updates already. Anyway, I downloaded from prezi.com/desktop and started installing, the installer says that 1.123 is already installed, so I skipped installing again.

Yes I have uploaded it to prezi.com it is http://prezi.com/68581
If I download this prezi and run it from prezi desktop, the fonts look correct but the error dialog box still appears. Curiously, the error box does not always show but 90% of the time it does.

Thanks very much for looking into this!

Best Regards Carl

P.S. I showed a Prezi in a meeting today and the viewers were blown away by the impression, so expect some new Prezi customers from Sweden soon. Thanks for a good product and for trying to help out.

köszönöm!

Hi Peter, I have shared it with you now. How do I download(export) from prezi.com/my. I can see this option in the prezi desktop application, but not in the web version.

Regards

Carl

Hi Peter, Zoli and all. I still have the same problem with Missing theme error. Can you please suggest what to do?
