Ambiguous in the namespace - vb.net

Question

I've updated a project from VB6 to VB.NET. Everything seemed to work fine, but now I'm facing errors related to the namespace when trying to build. Besides, I'm getting them on Form's designers, which have been automatically generated by Visual Studio. More specifically, the errors I'm facing involve the System.Drawing namespace and its internal structures (Point, Size, SizeF, etc).
I've checked it and I haven't found any other class that could be causing the conflict. I've also tried to delete the reference to the library and add it again, and to Clean the project, but the error is still there.
It's seems a problem similar to the one asked in this question, but I've tried the solutions answered there and haven't worked either. Any ideas of what could I do? This is driving me crazy and my whole project is stopped until I can fix that.
Thank you very, very much in advance.
EDIT: Added screenshots of the error and the code that's throwing it
Complete message of one of the errors: Error 18 'Point' is ambiguous in the namespace 'System.Drawing'. C:\Users\practiquesINF\Desktop\Projecte01_VBNET_V2\Upgraded\Frm_Files.Designer.vb 152 39 P_IF01
Complete code of one of the files that throws the error (as I've said, it's the designer of one of the forms and it has been generated automatically):

In case this is relevant for the question, the form was upgraded from VB6 to VB.NET using an automatic tool. Specifically, the VBUC by Mobilize.net (I do not intend to do this as spam, but to give as much information as I can. If I shouldn't have done this, I'll edit the post and delete the reference)

Answer 1

Finally, I've managed to solve it! It seems that one of the external libraries I was using was creating a conflict. As Visual Studio didn't tell my which one it was, I simply unreferenced them all and then referenced again only the ones that I needed at that exact moment.
The conflict seemed to be caused by one of the libraries of the GrapeCity's ActiveReport tool. As I had to upgrade the tool and it wasn't code that I had written (and it was quite poorly commented), I didn't know which ones were or will be needed, so I referenced more than necessary. And it seems that precisely one of the extra libraries (I'm not sure at all, but I think that it was one of the Chart ones) was the one causing the conflict.
Thank you all for your help! And sorry for not answering before, but I had to switch to another urgent project and I couldn't try the solutions until today.
