I have lost my" Welcome page", where you create a new company, open existing co. etc.

SUGGESTED

 I have lost the "WELCOME PAGE" , where you have choice of opening an existing company, creating a new company , create from back up etc.I think I may have caused this problem by deleting the " existing company I was working on " -with the  the address" C:\ new company.......SAI "because it would not load.   I got a message that said "cannot find any data files for this company. I highlighted the address at the bottom of the Open Existing company   on this welcome page, and deleted it.  I also ticked off the box at the bottom of this "WELCOME PAGE " Do not show......

Now I only have the choice of using  previous company, as on opening SAGE, it goes straight to data location, and I can open the files of the previous company I had worked on. I cannot create a new company  

..Is there a way to recover or bring back this welcome page.

Thanks.....
