We don't know what operation you are trying to perform that is "stuck on the 'this might take several minutes' stage"
Also, please be sure to state your operating system.
I'm using Windows 8 on a PC (laptop). Trying to install the 5.6 update that the software had been bugging me to do since I initially installed the program a few weeks ago. It had no trouble deleting the 5.2 version that was operating just fine on my PC and is now stuck on the first stage in the install wizard for the new 5.6 version. I'm hoping I can get it back.... it wasn't cheap.
Is that a clear enough question or should I include pictures?
I would restart the computer and try the installation again.
