We can close this topic. Reinstalling V2.00 didn't work, and I will set up a completely new installation. Luckily I found a survey export of the old survey, so that I at least know the questions...

Thanks again for the help!

When you say that you found an export of the old survey, is it an LSS?

Because then you should be able to import without a problem.

What happened to the reinstall? Why did it not work?

What you could try is making the new install of LS 3.0 and use a dump of the old database to see what happens. More than loosing the data can't really happen. If it works, great, basically an "update", if it doesn't, you'll just need to start over with the installation.

No, it's an Excel file. And there was a ton of error messages. The question for us is, if we really need LimeSurvey (or another survey platform), as we usually run one or two surveys per year... Plus, you can't easily embed it into another website (at least not V2.0)...

LimeSurvey 3 can be easily embedded via <iframes> into an website (many users using it like that)

The question for us is, if we really need LimeSurvey (or another survey platform), as we usually run one or two surveys per year...

Well, this decision non one can make for you.

Limesurvey isn't too expensive, I host mine for around 10 Euros per month on a VPS with 8GB ram and Plesk. For the occasional study this should be more than enough.

But if you really run 1-2 surveys per year, you could think about getting limesurvey Pro 1-2 per year and don't have to worry about hosting. Just export your survey as LSS and import it again later. I personally prefer to have it on my own server, and around 120-150 Euros per year aren't too much money I think. Of course CU comes on top of this. One could could live without it, but on the other hand it is very comfortable and while we could live without a sofa, most of us don't. And it is under 100 Euros per year I think. So all in all between 200-250 Euros, less if you also use the server for other things. Shouldn't kill any company.

Ok, I'll dig into this...

Thanks und danke!
