want to see a grown man cry..errors after changing framework 4.0 to 3.5

Long story short a few weeks ago my pc crashed and I lost my entire project. I have spent every spare minute getting back to where I left off.
I the last 2 days I have been working on crystal report using project datasets. I was running into an issue and it was suggested I change my framework version to 3.5 which I did. Now I have over 100 errors. Most appear to be related to table adapters or table adapter managers.

Is there anyway to recover from that?

Thanks

Change it back to 4.0?

That was my first thought. I changed it back to 4.0 and actually have a few more errors.
Seems like that is my mo...2 steps forward 3 back.
It looks like my only recourse is to start the project over AGAIN.

Maybe if you were to actually describe the errors rather than just say that they exist, then we may be able to determine the cause. That said, you could simply delete the whole typed DataSet and create a new one.

Sorry Jm
I am not allowed to visit forums on my work computer. I'm posting using my cell phone.
I am getting errors like.
TableAdapterManager is not a member of RAUAcctfileDataSetTableAdapters
Or
Type RiscApplUtility.RAUAcctfileDataSetTableAdapters.TableAdapterManager is not defined.

I basically see an error like that for every dataset.

Thanks

You could have a look in the DataSet code file and see if there is indeed a TableAdapterManager class definition in there. As I said though, deleting the DataSet and generating a new one should probably do the trick. As long as you haven't done significant customisation in the DataSet designer, it should be very quick.

I was able to get my datasets working again.

I followed the instructions in this guide:
Crystal Reports for Visual Studio .NET - Walkthrough - Reporting Off ADO.NET Datasets
So I created my report in designer using the same dataset I used on my form that contains the crystal report viewer that is using my report in question. Just to make it simple I only have a heading and a couple fields on my report.
I run my app and open my report, it has the data I am looking for, however its in a column format with the fields all bunched up, and it does not display my heading I added.
I did verify in my Crystal Report Viewer that I have the correct report selected.

Am I missing something when using a Project Dataset verse using an OLE dataset?

Here is the code behind my form with the crystal report viewer
