Can't open SMBX 1.4.4

[kemmyloopaling]

Usually SMBX 1.4.4 would work for me but suddenly when I opened Level Editor it loaded like normal until I got this error:

I tried restarting my computer and reinstalling SMBX but nothing worked. Can someone please help me?

(For people who can't see the picture) the error message is:
" Run-time error '9': Subscript out of range "

I also had that error when I tried SMBX 38A

Well, did you downloaded the patch of the game? There's a link at the SMBX 38A thread (Patch 2). That would probably fix your problem. You only have to download the file and extract it in the game folder. It has two files with the same name as others in the folder but you should replace them to install the patch. Then re-open the editor and see if the problem is fixed.

I just installed patch 2 over the two files (the exe and the dll) but I still get the same error message
